Abstract

This paper presented the dynamic characteristics and sensitivity analysis of the shaft of test machine based on finite element method and orthogonal design method. It is concluded that the top eight order natural frequencies (Hz) are 1673.3, 3666.6, 4421.8, 5713.8, 6612.9, 6656.8, 9550.9, 9617.5 based on modal analysis. The harmonic analysis results indicate that the third natural frequency is more likely to intensify initiation and propagation of the bending crack on the interference joint between specimen and shaft. It is concluded that the radius dimension parameters and the length parameters affecting more greatly the dynamic characteristics of shaft are R3, R1, R2 and L3, L4, L5, L1 through dynamic sensitivity analysis. The results above provide reference for dynamic optimization and design of the shaft and other shaft parts in the future.
