为解决自移式掘进机辅助支护设备立柱在实际工作中容易出现故障,给工作人员带来安全隐患的问题.采用传统的力学分析方法对立柱油缸稳定性、活塞杆强度和缸体强度进行验算,并用有限元软件对立柱进行静力学分析.研究结果表明:传统力学分析应用在立柱设计和改进过程中是合理的,有限元软件静力学分析方法可以验证传统力学分析的准确性,并且可以直观地显示最大应力点.两种方法互补使用,使设计过程更加合理,可以提高立柱的安全系数,为同类产品立柱设计和改进提供了参考依据.

@@@@In order to solve the column of self-motion assistanced powered support equipment for tunneling machine sometimes failure during practical work, a security risk to staff, analyse the stability of the column cylinder,a piston rod strength and cylinder strengthchecking,all using traditional mechanical, and static analysis of the column using finite element software. The results show that the traditional mechanical analysis is reasonable on column design, static analysis method of finite element software can verify the accuracy of the traditional mechanical analysis, and can visually display the maximum stress point. The two methods use complementary make the design process more reasonable, improve the safety factor of the column, provide a reference to column design or improve for similar products.
