The purpose of this paper is to propose a novel strategy of optimal parameters configuration and placement for sensitive equipment.

In this study, clamped thin plate is considered as the foundation form, and a novel composite system is proposed based on the two-stage isolation system. By means of the theory of mechanical four-pole connection, the displacement amplitude transmissibility from the thin plate to precision equipment is derived. For the purpose of performing optimal design of the composite system, a novel multi-objective idea is presented. Multi-objective particle swarm optimization (MOPSO) algorithm is adopted as an optimization technique, which can achieve a global optimal solution (gbest), and selecting the desired solution from an equivalent Pareto set can be avoided. Maximum and variance of the four transmitted peak displacements are considered as the fitness functions simultaneously; the purpose is aimed at reducing the amplitude of the multi-peak isolation system, meanwhile pursuing a uniform vibration as far as possible. The optimization is mainly organized as a combination of parameter configuration and placement design, and the traversal search of discrete plate is performed in each iteration for the purpose of achieving the global optimum.

An important transmissibility based on the mechanical four-pole connection is derived, and a composite vibration isolation system is proposed, and a novel optimization problem is also defined here. This study reports a novel optimization strategy combined with artificial intelligence for parameters and placement design of precision equipment, which can promote the traditional view of two-stage vibration isolation.

Two-stage vibration isolation systems are widely applied to the vibration attenuation of precision equipment, but in these traditional designs, vibration participation of foundation is often ignored. In this paper, participation of foundation of equipment is considered, and a coherent new strategy for equipment isolation and foundation vibration is presented. This study shows a new vision of interdisciplinary including civil engineering, mechanical dynamics and computational science.

China has showed its eagerness in using its economic strength in the very recent years. Is China going to be a major sanctioning state like the United States or the European Union? This chapter argues that although there have been an increasing number of economic sanctions imposed by China with its expanding national interests and growing diplomatic problems, China will still keep a low profile in using economic sanctions because of the restraining factors such as the WTO rules, inherent problems in its economy, the pursuit of a good reputation and its strategy of peaceful development. Thus the frequency and tactics of using economic sanctions may vary according to its rising economy and changing international situation, but that will go in a very limited way.

The purpose of this paper is to introduce a method for (re)designing complex logistics networks, which interact with various governmental bodies (e.g. in FDA and USDA) for regulatory clearance and control purpose. The method (the e³‐control methodology) is demonstrated to be a useful approach to analyzing and redesigning international logistics procedures in reaction to a technological innovation in a government‐business (G2B) network.

An action research method relying on Living Lab study was used in this research. To illustrate and better understand the application of the e³‐control methodology, the authors place the development of e³‐control as a design tool for deploying the pharmaceutical case. The authors collected data with multiple methods including workshops, semi‐structured interviews and document analysis.

The e³‐control methodology has been successfully applied in this paper to carry out a step‐by‐step redesign for an international pharmaceutical logistics network. It was found that a win‐win situation can be achieved if business and government see each other as partners and share the responsibility of carrying out government regulatory and Customs controls. In this situation, Customs administrations can be relieved from redundant control tasks, and businesses will be rewarded with simplified procedures.

The authors' e³‐control methodology is an innovative redesign methodology for analyzing and redesigning business logistic networks including government agencies. With this approach, one can achieve a clear overview on critical problems within the logistics chains; disclose unclear procedures and in the meanwhile take into consideration the different concerns of the partners within the network.

Engineering composite laminates/structures are usually subjected to complex and variable loads, which result in interlayer delamination damage. However, damaged laminate may cause the whole structure to fail before reaching the design level. Therefore, the purpose of this paper is to develop an equivalent model to effectively evaluate compressive residual strength.

In this paper, taking carbon fiber reinforced composite T300/69 specimens as the study object, first, the compressive residual strength under different impact energy is obtained. Then, zero-thickness cohesive elements, Hashin failure criteria and Camanho nonlinear degradation scheme are used to simulate the full-process simulation for compression after edge impact (CAEI). Lastly, based on an improved Whitney–Nuismer criterion, the equation of edge hole stress distribution, characteristic length and compressive residual strength is used to verify the correctness of the equivalent model.

An equivalent relationship between the compressive residual strength of damaged laminates and laminates with edge hole is established. For T300/69 laminates with a thickness of 2.4 mm, the compressive residual strength after damage under an impact energy of 3 J is equivalent to that when the hole aperture R = 2.25 mm and the hole aperture R = 9.18 mm when impact energy is 6 J. Besides, the relationship under the same size and different thickness is obtained.

The value of this study is to provide a reference for the equivalent behavior of damaged laminates. An equivalent model proposed in this paper will contribute to the research of compressive residual strength and provide a theoretical basis for practical engineering application.

The CL60 steel wheels of subway vehicles operating on specific lines require frequent refurbishment due to rapid wear and tear. Considering this issue, MoS₂-based and graphite-based solid lubricants are used to reduce the wear rate of subway wheels and extend their service life.

Under laboratory conditions, the effect of MoS₂-based and graphite-based solid lubricants on the friction and wear performance of subway wheels and rails was evaluated using a modified GPM-60 wear testing machine.

Under laboratory conditions, MoS₂-based solid lubricants have the best effect in reducing wheel/rail wear, compared to the control group without lubrication, at 2 × 105 revolutions, the total wheel-rail wear decreased by 95.07%. However, when three types of solid lubricants are used separately, the hardness evolution of the wheel-rail contact surface exhibits different characteristics.

The research results provide important support for improving the lifespan of wheel and rail, extending the service cycle of wheel and rail, reducing the operating costs of subway systems, improving the safety of subway systems and providing wear reduction maintenance for other high wear mechanical components.

The experiment was conducted through the design and modification of a GPM-60 testing machine for wear testing. The experiment simulated the wheel-rail contact situation under actual subway operation and evaluated the effects of three different solid lubricants, MoS₂-based and graphite-based, on the wear performance and surface hardening evolution of subway wheel-rail.

The purpose of this paper is to present the influence of inter-turn short circuit faults (ITSF) on electromagnetic vibration in high-voltage line-starting permanent magnet synchronous motor (HVLSPMSMS).

In this paper, the ampere–conductor wave model of HVLSPMSM after ITSF is established. Second, a mathematical model of the magnetic field after ITSF is established, and the influence law of the ITSF on the air-gap magnetic field is analyzed. Further, the mathematical expression of the electromagnetic force density is established based on the Maxwell tensor method. The impact of HVLSPMSM torque ripple frequency, radial electromagnetic force spatial–temporal distribution and rotor unbalanced magnetic tension force by ITSF is revealed. Finally, the electromagnetic–mechanical coupling model of HVLSPMSM is established, and the vibration spectra of the motor with different degrees of ITSF are solved by numerical calculation.

In this study, it is found that the 2np order flux density harmonics and (2 N + 1) p order electromagnetic forces are not generated when ITSF occurs in HVLSPMSM.

By analyzing the multi-harmonics of HVLSPMSM after ITSF, this paper provides a reliable method for troubleshooting from the perspective of vibration and torque fluctuation and rotor unbalanced electromagnetic force.

Based on the conservation of resources view, the objective of this paper is to examine the relationship between abusive supervision and workplace thriving. Further, this study investigates the underlying mechanisms role of agentic work behaviors (i.e. task focus, heedful relating) and moderating role of employee's core self-evaluations.

Using a time-lag approach, data are collected from 360 full-time employees enrolled in an executive development program in a large university of China. To test the proposed model, data analysis is carried out through Statistical Product and Service Solutions (SPSS) and Analysis of Moment Structures (AMOS).

The results show that abusive supervision negatively influences workplace thriving. Further, the findings also confirm the mediating role of agentic work behaviors and the moderating role of core self-evaluations between the relationship of abusive supervision and thriving.

Based on study findings, this study draws the attention of managers toward the new deleterious outcomes of abusive supervision. Hence, to nurture a thriving workforce, organizations should keep abusive behaviors under keen observations to minimize their frequent occurrences. Further, it is proposed that hiring employees with higher core self-evaluations can mitigate the injurious effect of abusive supervision.

This is the first attempt to our knowledge to untapped the abusive supervision-thriving relationship via the underlying mechanisms of two agentic work behavior's and core self-evaluations as a moderator enriches the extant body of knowledge and provide valuable insight into the abusive supervision and workplace thriving literature.

The purpose of this paper is to investigate the effect of perceived fit on thriving and reveal the potential moderator and mediator of this effect by drawing on self-determination theory. Moreover, to adapt the research to Chinese contexts, a four-factor conceptualization of perceived fit is suggested.

The paper includes two studies. Study 1 involved a survey that collected data from 531 employees to investigate the relationship between perceived fit and thriving and the moderating role of personal goal commitment. Study 2 consisted of a scenario-based experiment in which 240 university students were recruited to strengthen the main findings of Study 1 and test the underlying mechanisms of the effect of perceived fit on thriving.

Study 1 shows that perceived fit positively relates to thriving, and personal goal commitment plays a moderating role in this effect. In addition, it demonstrates the validity of the proposed four-factor conceptualization of perceived fit in Chinese contexts. Study 2 strengthens the proposition of the positive effect of perceived fit on thriving and identifies the mediating roles of self-determination in this effect.

This paper contributes to the literature on thriving and fit by exploring new antecedents of thriving and extending the dimensions of perceived fit.
