Automotive and aerospace manufacturers using Ometron's latest SPATE 4000 scanning stress-pattern analyser will now better understand the stresses undergone by critical components such as suspension arms and vehicle bodies.

Advances in SPATE's software now mean that the non-contact instrument can examine dynamic mechanical stress in sub-systems and components as they are moving under load (see Plate 3).

Measuring the stress pattern on a moving object has been possible for some time with SPATE, but any motion compensation has only allowed for simple translation of the component. More complex movement, such as that which can occur in a suspension arm under load caused blurring of the image, often to the point where the data was invalid.

SPATE 4000AMC (Advanced Motion Compensation) can deal with motion which is not constant across the object being measured. The compensation can be set up for several points on the image and is then interpolated between these points over the rest of the surface. Thus a suspension arm where one part is moving vertically, while another part is static can now be measured.

AMC is available as standard on all the latest generation SPATE 4000s, but can also be retrofitted on all existing SPATE 4000 systems as an upgrade.
