摘　　要：履带式拉挤机拉挤速度波动影响牵引装置的稳定运行,对管材质量也会造成影响。为了满足恒定拉挤速度的控制要求,以履带式拉挤机牵引装置的驱动系统为研究对象。首先,建立驱动系统数学模型,画出传递函数方块图,并提出随机权重的改进海鸥优化算法控制策略;然后,在MATLAB/Simulink软件中搭建驱动系统仿真模型,并对其在不同工况下的稳定性进行仿真,仿真结果表明,采用随机权重的改进海鸥优化算法后,驱动系统响应速度快、控制精度高,更能满足恒定拉挤速度的控制要求;最后在履带式拉挤成型试验平台进行试验验证,结果表明,仿真拉挤速度与试验拉挤速度的变化趋势基本一致,验证了仿真结果的正确性。The pultrusion speed fluctuation of the crawler pultrusion machine affects the stable operation of the traction device and also affects the quality of the pipe.In order to meet the control requirements of constant pultrusion speed,the driving system of the crawler pultrusion machine traction device was taken as the research object.Firstly,the mathematical model of the driving system was established,the transfer function block diagram was drawn,and the improved seagull optimization algorithm control with random weight was proposed.Then,the driving system simulation model in MATLAB/Simulink software was built,and its stability under different working conditions was simulated.The simulation results showed that after using the improved seagull optimization algorithm with random weights,the drive system had fast response speed and high control precision.It can better meet the control requirements of constant pultrusion speed;finally,the experimental verification was carried out in the crawler pultrusion procduction test platform,and the results showed that the variation trend of the simulated pultrusion speed was basically the same as that of the test pultrusion speed,which verified the correctness of the simulation results.
