主轴承壁强度计算载荷获取方法对比研究

Comparison of Two Methods to Main Bearing Loads in Process of Simulating MBW HCF Safety

针对某机型柴油机机体主轴承壁,分别采用两种不同的主轴承载荷处理方式对机体主轴承壁强度进行计算分析,对比得出两种载荷处理方式对计算结果的影响,为柴油机设计过程中较快速、合理地对机体主轴承强度进行评价、优化提供参考。

For main bearing wall of one engine,using two methods of simulating main bearing loads to calculate MBW HCF safety,find out difference of the two methods in process of simulating MBW HCF safety.If the difference of the two methods could be considered reasonably in process of FEA of main bearing wall,the design of main bearing wall could be improved effectually.
