Finite element analysis of rubber diaphragm of the small diaphragm vacuum pump by ANSYS

Gao Jun-ji

Abstract

This paper analyzes the actual working condition of rubber diaphragm,and builds its axial symmetry 2D and 3D finite element model.The rubber diaphragm of diaphragm vacuum pump was analyzed and calculated by ANSYS software,and the simulation results were verified through theoretical analysis of mechanical model and experiments.The physical design of rubber diaphragm was optimized based on analysis results.
