OEMs and Tier 1 and tier 2 suppliers are under increased pressure to meet with 5 years and 100 thousand miles warranty on each and every rubber and plastic component in a passenger vehicle. With customer expectations for 100% reliability there is a need to fully test all the design, prototyping stage . Rubber mounts and vibration isolators are used to connect a vehicle’s engine and transmission to its chassis.
They are required to reduce the transmission of vibrations, providing the desired ride characteristics and protecting the rigid frame. The elastomeric material used in these components tends to naturally degrade over a period of time due to harsh conditions in addition to material degradation. Testing the properties of these mounts under such conditions is critical to make sure that the components meet the expectations. Choosing the correct test parameters required to perform this type of automotive component tests reliably can be challenging. We have more than a decade of experience in the design, analysis and testing of these rubber elastomer mounts.
