Finite Element Analysis of the Compressor Cylinder Head Bolt
摘要
Abstract
The compressor cylinder head bolt is used for the cylinder head,gasket,cylinder body and other important removable parts join together,whether it meet the design requirements directly determines the realization of the compressor seal performance,so it is very important to check and analysis for the bolt.Based on the theoretical calculation,finite element analysis is used to check the design validity in this paper.On the basis of theoretical analysis of this paper,the FEA method based on screw thread contact section checks the connecting bolt at the cylinder head,not only be the same as the theoretical calculation of bolt strength as a result,and make the bolt that on the stress distribution under different working conditions and elongation to get better.Due to this way to simplify the threaded portion,bolt greatly improve the efficiency of modeling,reduce the calculation time,and also can get the accurate fruit of threaded parts of stress and strain.As a result of different cavity pressure stress distribution of the different parts of the bolt,the page provide the basis for design and optimization of bolt,also the importantsolution method for analysis of bolt connection of the similar problems.关键词
