【摘要】 应用有限元方法对ZH1105WG型单缸柴油机机体进行了动态特性分析，并以柴油机气缸燃气压力及运动部件惯性力为主要因素确定了机体的激励力。在此基础上，对柴油机机体进行了振动响应计算，从而为机体的结构改进提供了依据。更多还原

【Abstract】 The application of Finite Element Method (FEM) to analysing the dynamic characteristic on the block of model ZH1105WG single-cylinder diesel engine is presented in this paper. The gas pressure and inertia force of moving parts in the diesel engine are considered as the major exciting forces on the block. Based on it, the vibration response of the engine block is predicted by FEM, Which provides the basis for modifying engine block design.更多还原
