摘　　要：建立了惯性冲击马达的动力学模型,该模型考虑了摩擦的非线性。应用MATLAB/Simulink软件进行了仿真分析,得到了马达的位移曲线、平均速度-电压曲线和平均速度-频率曲线,最后设计了实验装置进行了验证。实验结果表明,惯性冲击马达的运动速度与驱动信号的幅度和频率基本上呈线性规律变化,与理论计算相比,仿真结果更接近马达的实际运动过程,因此所建立的模型可以用于预测惯性冲击马达的运动性能。A model of impact drive mechanism （IDM） was built,in which the friction nonlinearity was considered.The simulation model was developed by utilizing MATLAB /Simulink.A group of curves were obtained based on the model,including the relationship of displacement and time,the relationship of average velocity and voltage and the relationship of average velocity and frequency.An experiment was made to verify the simulation results.The experimental results show that the velocity of impact drive mechanism increases linearly as the voltage or the frequency is increased basically.The simulation results are more coincident with the fact than the theoretical values.The model can be used to predict the motion performance of the IDM.
