摘要
采煤机摇臂在变幅、重载作用下,经常发生失效,为了克服这一工程问题,采用ANSYS Workbench对于链传动采煤机摇臂进行有限元分析,通过添加链传动采煤机摇臂模型的材料属性、网格划分,确定边界条件。研究结果表明选用的材料,摇臂与液压缸铰耳配合可靠,能保证摇臂的正常工作,延长使用寿命。该方法为链传动采煤机摇臂稳定性分析提供了一种有效的方法。
In order to verify the feasibility of the Ansys Workbench for the finite element analysis of the rocker ann of the chain drive, the rocker model is meshed by adding the material properties of the rocker model of the chain drive shearer, and the boundary condition is determined to obtain the stress Cloud and strain cloud, according to the results of the analysis. Through the analysis of the results, can be used in the manufacture of rocker arm with the hydraulic cylinder hinge ears, the use of more reliable materials, or appropriate to change the structure here to ensure the normal operation of the rocker arm to extend the service life. This method provides a direct and effective new method for the stability analysis of the rocker arm of the chain drive.
