Defence equipment and many industrial structures have
to be capable of withstanding shock loadings. The response of a design may be
highly dependent upon the surrounding structure or medium, which may modify the
dynamic characteristics of the design and the loading applied to it. Isolation
mounts are frequently used to reduce the shock loads applied to a design. The
behaviour of these can be complex, and in some instances can only be
characterised by physical Testing. Eatec has experience
of testing of shock mounts and developing mathematical representations of their
behaviour in shock and vibration environments. These representations can be
added to a finite element model for analysis of the system.
