针对重型采掘装备振动测试中传感器布置优化的问题,建立了以连续采煤机为研究对象的刚柔耦合虚拟样机模型。在虚拟样机模型中设置截割滚筒载荷激励及传感器虚拟测点,计算结构各阶模态振型及各测点振动响应能量。分析结果表明,通过模态振型及模态运动能数值可以有效判断传感器布置数目,优化传感器布置位置,并为后续连采机振动测试实验提供理论依据。 Aimed at the optimization of sensor arrangement in vibration test of heavy mining equipment, a rigid-flexible coupling virtual prototype model with continuous shearer as research object was established. In the virtual prototype model, the cutting drum load excitation and the sensor virtual measuring point are set, and the modal vibration modes and the vibration response energy of each measuring point are calculated. The analysis results show that the number of sensor arrangements can be effectively judged by modal vibration mode and modal kinetic energy values, and the sensor placement can be optimized. The theoretical basis for the subsequent vibration test of continuous mining machine is provided.
