基于UG建立了掘进机整机三维实体模型,并在ANSYS中生成叉形架柔性体的模态中性文件,将其导入动力学仿真软件Adams建立了掘进机刚柔耦合系统。通过对该系统进行动力学仿真分析,得到典型工况下,叉形架各铰结点动态载荷曲线及应力云图,为掘进机叉形架的优化设计提供了一定的理论基础和量化依据。 Based on UG, a three-dimensional solid model of roadheader was set up, and a modal neutral file of fork body flexible body was generated in ANSYS, which was imported into the dynamic simulation software Adams to establish the rigid-flexible coupling system of roadheader. Through the dynamic simulation analysis of the system, the dynamic load curve and the stress cloud chart of the hinge points of the yoke under typical working conditions are obtained, which provide some theoretical basis and quantitative basis for the optimal design of heading machine fork yoke.
