Abstract:
First of all, we would like to introduce the basic engine mounting layout analysis by the equation of motion and the FEM simulation. For the heavy-duty vehicle, the 4 supporting points engine mounting is basic, but the other types, such as 3 and 5 points also exist. So, we researched what is the best layout to isolate the vibration and support the engine dynamic torque among 11 layout systems by the analyses of eigen value, the frequency response, and the transient response. According to these above studies, when considering all the various criteria, the best engine mounting is the sloping layout. It is the 3rd best for the reduction of engine idling vibration and is the 2nd best against the shock torque.
