Analysis of the Transmission of Engine Vibration to the Body by the Mechanical Impedance Method 740163

The route of engine vibration transmission to the vehicle body is regarded in this paper as a tandem system comprising engine mount, cross members, and other chassis elements. Therefore, on this premise, vibration characteristics have been analyzed by the mechanical impedance method, and parameters identifying the resonant frequencies of the powerplant, the spring content, and damping coefficient of mount rubber interfaces have been clarified. The equations and formulas presented in this paper offer solution to the problem of body vibration.
