摘要
基于刚-柔耦合多体接触动力学理论，对采煤机截割部传动系统进行了研究，给出了其模型参数的确定方法。在RecurDyn软件环境中建立了截割部传动系统刚柔耦合多体接触动力学模型，并施加MATLAB计算出的基于实际工况的载荷。在仿真环境下直观动态地描述了齿轮啮合接触过程，计算出了各级齿轮的动态等效应力，并根据仿真结果对齿轮进行了优化。解决了大型机械传动机构进行柔性接触仿真的难题，增加了虚拟样机技术研究的可靠性，揭示了齿轮传动系统的刚度激励与啮合冲击激励引起响应的周期性波动现象。
Abstract
To study the transmission system of the coal winning machine cutting part, the theory of rigid-flex coupled multi-body system dynamics is applied, a method for determining the model parameters is presented. The transmission system dynamics model of rigid-flexible coupling multi-body contact was built in the RecurDyn software environment and exerted in the MATLAB to calculate the actual condition of the load. In order to optimize the simulation results of the gear , the meshing process is described directly and dynamically and the dynamic equivalent levels of gear stress is calculated under the simulation environment. The problems of large mechanical transmission mechanism with flexible contact simulation are solved and proved in the reliability of virtual prototyping technology, more over periodic fluctuations are revealed for the stiffness excitation and meshing gear transmission system.
