Modal and Harmonic Response Analysis of Subway Gearbox Housing

Abstract

Box housing plays an important role in the course of the entire operation of the gearbox in the subway,not only withstanding the bearing’s load,also the extemal excitation and noise has an important influence. Modeled the box housing by the Pro / E,The three- dimensional solid modeling of the subway gearbox housing is carried out through the Pro / E,then imported into the Workbench for finite element modal analysis,the natural frequency and vibration mode are got,and the results of experimental mode analysis are compared with the finite element modal analysis,the feasibility of the modal analysis is test. The harmonic analysis is carried out based on the finite element modal analysis,the anti- vibration performance under the effect of different frequency are obtained. Which can arrange the reasonable housing structure,and a reliable basis for the further analysis of the dynamic response of the gearbox is provided.
