| 摘 要： | 为延长采煤机的使用寿命,以针对含硫化铁矿结核体薄煤层的某型采煤机摇臂壳体为研究对象,利用Matlab生成螺旋滚筒的瞬时负载文件,建立基于MSC Adams的采煤机截割部刚柔耦合有限元模型.应用ANSYS与MSC Adams之间的双向接口,实现柔性体对机械系统动力学行为影响的系统仿真,仿真精度得到提高.通过MSC Adams输出ANSYS所需要的载荷文件,对摇臂壳体进行瞬态动力学分析,并应用MSC Fatigue对其进行疲劳分析,发现该采煤机摇臂壳体的薄弱部位.该方法在产品开发的早期就能对摇臂壳体的疲劳特性有所认识,为采煤机设计提供新思路.

| Abstract: | To extend the service life of shearers,taking the ranging arm of a shearer which is designed for thin coal seam containing pyrites as the research object,Matlab is used to create the transient load files of the shearer spiral cutting drum,and a rigid-flexible coupling finite element model about the shearer cutting section is built based on MSC Adams. Considering the effects caused by flexible bodies on the mechanical systematic dynamics behaviors,a system simulation is implemented using the bidirectional in... |
