The Modal Analysis of MWM395 Engine Block
摘要
Abstract
Block is the base structure of the diesel engine.It can notablyinfluence the radiation of the engine.In this paper, the mode character of MWM395 engine block is analyzed with the finite element analysis on the platform of I-DEAS.At first,A 3-D model of engine block was established,then the model results were abtained by Lancozas algorithm.In the case of less change of engine block's structure,different kinds of block model are estallished and their calculations are solved.Through the compare of different kinds of cases,a way for improving rigidity of MWM395 engine block and a credible dynamic model for the dynamic analysis of MWM395 engine block at the same time are provided.关键词
