摘要

通过Pro/E三维软件对地铁齿轮箱箱体进行三维实体建模,然后导入Workbench中对箱体进行有限元模态分析,得出箱体的固有频率和振型;进行实验模态分析与有限元模态分析结果进行对比,检验箱体模态分析方法的可行性;在有限元模态分析的基础上进行谐分析,得出不同频率作用下箱体结构抗振性能。从而在设计过程中可以对箱体结构进行合理布置,增加箱体刚度,并为进一步进行齿轮箱的动态响应分析提供可靠依据。

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.
