Elastomer mounts have the particular feature that their properties cha
nge under the influence of dynamic and static stress, as well as envir
onmental influences. These changes can be seen particularly clearly wh
en comparing older vehicles with a new vehicle, To evaluate such chang
es in properties, static and dynamic tests have been carried out in th
e laboratory under environmental conditions, comparative to road tests
, The results show which stresses and environmental influences cause t
he properties to change significantly. Furthermore, they make clear th
at - as a rule - a simple laboratory test cannot be defined which effe
cts exactly the same property changes as a road test, with regard to t
he change in static and dynamic characteristic values, Depending on th
e type of mount and elastomer used, however, laboratory tests can be s
elected which provide useful evidence as compared with driving tests.
The amount of costly road tests can be clearly reduced as a result.
