Abstract
Vibration character analysis for the powertrain system of a diesel engine has been accomplished by means of the FEM based on multi-body dynamics model. The loading conditions applied to the diesel engine and the gear box are very similar to the practical situation, for example the connections between the engine and the gearbox are simulated by preload bolts and the headstock loads are simulated by the compressive elements without extension. The results show that the vibration level in the surface of the bottom shell of the engine is the highest. So, it is suggested that the ribbings be used in the side wall of the bottom shell. Since the vibration level of the engine surface increases gradually from the bottom to the top of the engine, it is suggested that composite material and high damping material be used to reduce the vibration level of the engine.关键词
