摘　　要：为探讨利用现代设计技术进行内燃机结构部件动态设计的方法和途径 ,本文以某大功率柴油机曲轴为例 ,结合CAD三维实体建模和有限元结构离散、模态分析、动响应计算、灵敏度分析、结构动力修改以及CAD二维工程布图等几方面内容 ,系统总结了利用现代设计技术对内燃机零部件进行动态设计的方法和流程。实例表明 ,利用本文的方法和技术 ,有效改善了结构的动态响应 ,提高了结构的可靠性和耐久性。本文针对内燃机曲轴动态设计的方法和流程 ,对其它机械产品的动态设计也具有参考价值。In order to research the approach of structural dynamic design for components of I.C.E., this paper takes a heavy-duty engine's crankshaft as an example, coupling with 3D CAD modeling and the FEA meshing, mode analysis, calculation of dynamic response, sensitivity analysis, model dynamic modify and 2D engineering drawing etc.. The systematic methods of structural dynamic design for components of I.C.E are summarized. It shows that the method and technology used in this paper can improve the durability and reliability of I.C. engine and the structural dynamic response .The method and process also can be used as a good reference in dynamic design of other mechanical products.
