摘　　要：为了研究冲击动载荷条件下,考虑采煤机截割部电动机机械特性时截割部传动系统的动力学响应,在Adams中建立了采煤机截割部传动系统模型,在Simulink中建立了截割部电动机模型,通过Adams/Controls模块将传动系统与电动机模块联合,进行机电耦合仿真并对结果进行分析。结果表明,机电耦合模型能够对施加的载荷进行实时反馈,随着冲击载荷的施加,电机的输出及各部件的角速度会降低,加速度波动会大幅度增加。各部件角速度和加速度频谱符合理论计算,验证了模型的准确性。对采煤机截割部传动系统的分析和优化提供了依据。In order to study the dynamic response of the cutting part transmission system under the condition of impact dynamic load,considering the mechanical characteristics of the cutting part motor of the shearer,a transmission system model of the cut⁃ting part of the shearer was established in Adams,and a motor model of the cutting part was established in Simulink,the trans⁃mission system and the motor model were combined through the Adams/Controls module,and the electromechanical coupling simulation was performed and the results were analyzed.The results show that the electromechanical coupling model can provide real-time feedback to the applied load.As the impact load is applied,the output of the motor and the angular velocity of each component will decrease,and the acceleration fluctuation will increase greatly.The angular velocity and acceleration spectrum of each component conform to the theoretical calculation,which verifies the accuracy of the model.It provides a basis for the analy⁃sis and optimization of the transmission system of the shearer cutting part.
