主要对M201型采煤机摇臂壳体进行有限元分析,计算摇臂壳体在最大采高和最低窝底位置极限状态时,网格划分大小不同时的应力及位移,并进行比较、分析,确定摇臂壳体在何时的应力值趋于稳定及合理应力值的大小,检验摇臂壳体的强度、刚度是否满足设计要求,是否有足够的安全系数,并为同类摇臂壳体的设计验证提供参考依据。
Mainly on the M201 shearer rocker shell finite element analysis of the rocker arm shell in the maximum height and minimum nest bottom position limit state, the mesh size of the different sizes of stress and displacement, and compared and analyzed , To determine the rocker arm shell when the stress tends to be stable and reasonable size of the value of stress, test the strength of the rocker arm shell, the rigidity meets the design requirements, whether there is sufficient safety factor, and for similar rocker shell Design verification provides a reference.
