Abstract: Most research and development of internal combustion engine mounting system is to achieve and improve the primary vibration isolator of the engine from the chassis. The purpose of this study is to gain a better knowledge and evaluate the vibration assessment and transmissibility of a rubber engine mount (REM) in vibration suppression of a vehicle engine. The experimental test stand is designed to present the simulation of the actual operating condition which was used on a Lada 2107 vehicle's engine and manual gearbox supported by three types of engine mounting. An improved understanding of the vibration signal is required for early detection of transmissibility. Vibration isolation performances of the engine mount system, such as acceleration and transmitted force, are experimentally evaluated and they are presented in both time and frequency domains. The engine mounting transmission ratios (EMTR) are presented at various engine operating speeds with different mount types. Moreover, the results indicate that root mean square (RMS) of EMTR performance is improved by 14%, 16.5%, 17.9%, 18.6% and 19% at an engine speed of 800 rpm, 1,600 rpm, 2,400 rpm, 3,100 rpm, 4,000 rpm, respectively by using the proposed engine cone and shear mounting system associated with the tuned vibration absorber modification.
