Dynamic Response and Structural Optimization Analysis of Twin-Screw Air Compressor Shell
In order to further explore the dynamic response characteristics of the twin-screw air compressor shell,a three-dimensional model of the shell structure of the twin-screw air compressor used in a coal mine was established.The modal analysis and dynamic response analysis were carried out through the finite element analysis method.The analysis results showed that although there was no resonance risk in the shell structure,the vibration of the right end cap and the exhaust seat was relatively severe.There are still adverse effects on practical application.The results show that the maximum vibration displacement and maximum vibration velocity of the optimized shell structure have been significantly reduced,respectively,by 6.04％and 8.42％.The effect is more significant.
