Study on the Deformation Analysis in the Compact Diaphragm Boot of A C. V. Joint by Finite Element Analysis

Abstract

The constant velocity (CV) joint boots in vehicles protect the CV joints, which are axle connection parts that transmit the axial rotary motion caused by the steering system. In order to mitigate the issues concerning CV joint boots, the boot was newly designed to enable production using the injection molding method and to reduce the inner space by more than 30%, and the operability and durability of the newly designed boots were verified based on a comparative analysis with the conventional product using the finite element method (FEM). A finite element analysis was conducted using commercial software, MSC. Marc, and the finite elements for three models, including the Old Model, New Model 1 and New Model 2, were generated for the analysis. The analysis results showed that the maximum stress values were similar in all three models, and thus, it is deemed that there will be no problems in durability and reliability resulting from the design change.
