Dynamic characteristic analysis of high precision gear test box

Abstract

This paper analyzed the dynamic characteristic of high-speed precision gear test stand box. According to the required parameters to establish the three-dimensional solid model of various components, using the virtual prototype simulation technology to verify the mutual movement of each constituent part, then using the dynamic excitation method to process modal analysis on the vibration characteristic of key components, solving the dynamic load factor, analyzing the dynamic load curve under the conditions of different speeds, the results proved that the elastic deformation and stress value of test stand box are within the allowable range under the action of test load, the box's natural frequency was much larger than the frequency range when resonated with the revolving shaft of text stand. It provided a useful analysis result for the optimal design of test stand. © 2012 Springer-Verlag.
