新1130柴油机机体结构设计与分析

Analysis of Structure Design of a New 1130 Diesel Engine Block

重点介绍新1130机体设计、分析和改进的经验。在新1130系列柴油机的设计中,充分运用CAD,CAE手段,对其机体、曲轴、连杆等主要零部件进行了多方案的有限元分析。对机体这一受力复杂的零件,采用有限元分析法对机体进行了有效的应力分析,从中找出最危险的部位进行改进设计,使结构设计更合理,强度和刚性更好、更一致,整机可靠性更好,零件质量更轻。

This paper focuses on introducing experiences of design, analysis and improvement of a new 1130 block. The finite element analysis is carried out in main components, such as block, crankshaft, connecting-rod and so on by using CAD and CAE in design of new 1130 series engine. The finite element analysis is used to analyze effectively the stress of the block which is a component endured complex forces so that the most dangerous part is found out to be improved. The improved component is rational in structure design and lighter in quality, has better intensity and rigidity and the whole engine is more reliable.
