Deformation of NVH Materials Used in Transmission Shift Cable Systems Through Their Life Cycle

As noise and vibration are constantly being evaluated and targeted for improvement in automotive engineering, it is important to understand the performance capabilities of the materials used in transmission shift cable systems to reduce noise, vibration, and harshness (NVH). Energy absorbing materials are commonly used in push-pull cable systems for isolating terminal attachments and conduit abutments. Integrated into the cable system, these materials isolate the vehicle's shift mechanism from its external attachments at the transmission. When sufficient heat and load are applied in cycles, these materials will deform over time. As the components deform in shape there is a reduction in a shift system's ability to transmit motion.
