Investigation into Qualitative Dynamic Characteristics Analysis of Hydraulically Damped Rubber Mount for Vehicle Engine 2009-01-2132
Hydraulically damped rubber mount (HDM) can effectively attenuate vibrations transmitting between automotive powertrain and body/chassis, and reduce interior noise of car compartment. This paper involves an analytical qualitative analysis approach of dynamics characteristics of HDM. Analysis of experimental results verifies the effectiveness of the qualitative analysis approach. Frequency- and amplitude-dependent dynamic characteristic of HDM are investigated to clarify working mechanism of HDM. The presented qualitative analysis approach provides a convenient performance adjustment guideline of HDM to meet vibration isolation requirements of powertrain mount system.
