基于Matlab、UG、ADAMS和ANSYS联合构造的协同仿真环境,建立了采煤机截割部的刚-柔耦合虚拟样机模型,充分考虑了弹性变形体在复杂机械系统仿真中的影响,解决了输入负载的模拟和仿真边界条件的确定等关键技术问题。基于截割部的刚柔耦合协同仿真分析,得到了关键零部件应力分布与变形情况,发现了摇臂壳体的薄弱环节,并提出了优化方案,优化后壳体应力分布情况得到了明显的改善,为采煤机截割部的结构设计优化提供了依据,对深入研究截割部传动系统的动态性能具有重要价值。
Based on the co-simulation environment of Matlab, UG, ADAMS and ANSYS, a rigid-flexible coupled virtual prototype model of shearer cutting section is established. The influence of elastic deformation body in complex mechanical system simulation is fully considered. Load simulation and simulation of the boundary conditions to determine the key technical issues. Based on the rigid-flexible coupling co-simulation analysis of the cutting part, the stress distribution and deformation of the key parts are obtained, the weak links of the rocker arm shell are found, and the optimization scheme is proposed. The stress distribution of the shell after optimization is obviously Improve, provide the basis for structural design and optimization of the cutting department of shearer and have important value for further study of the dynamic performance of the transmission system of the cutting unit.
