摘要

为了提高高强化柴油机的设计效率

以某大功率柴油机机体为例

对机体进行了动力学仿真研究.在机体有限元模型上施加模拟实际工作状态的边界约束和载荷条件

利用振型叠加法对其进行动态响应分析

并与设计指标对比

采用了灵敏度分析方法

对原机体结构参数进行了动力修改.计算出机体的动态特性参数对设计变量的参数灵敏度程度

选择那些对动态特性影响较大的设计参数作为修改参数.修改后的机体

动态响应结果能够满足给定的设计指标.

Abstract

To improve the design efficiency of highly-intensified diesel engine

dynamic simulations are made on the engine block of a high-power diesel engine.Boundary restrictions and loading conditions simulating the actual operations are exerted on the finite element model of the engine block and its dynamic responses are analyzed through the superposition method of mode of vibration.Some structure parameters are subjected to amend to fulfill the design requirements.The to-be-amended parameters are selected from all the parameters according to the sensitivity analysis method.The parameters which influence the dynamic properties greatly are selected according to the variation of the dynamic properties with each parameter.Thus the dynamic properties of the amended engine block could satisfy the design requirements.
