采煤机在恶劣环境下工作时,受到复杂的力作用,增加了采煤机样机试制难度,因此,采煤机物理样机制作前,借助虚拟样机技术对产品进行优化处理,获得符合要求的产品。介绍了柔性体虚拟样机动力学及运动方程的推导过程,利用Pro/E、ADAMS和ANSYS三维建模及仿真软件,建立采煤机截割部刚柔耦合模型,通过对采煤机摇臂动力学仿真分析,获得摇臂受力以及受力变形信息,仿真结果证明本方法可为采煤机截割部设计提供依据。 Shearer working in harsh environment, subject to complex forces, increasing the prototype of the shearer difficult trial, therefore, before the shearer physical prototype production, the use of virtual prototype technology to optimize the product to obtain the desired product . The derivation process of the dynamics and equations of motion of the flexible body virtual prototype is introduced. The rigid-flexible coupling model of the cutting section of the shearer is established by using Pro / E, ADAMS and ANSYS 3D modeling and simulation software. The simulation results show that the method can provide the basis for the design of shearer cutting section.
