摘要:
针对DPT型接触网检修车现有的进口三平台作业装置只能定速运行的缺陷,文章采用PWM控制技术对其进行了运行速度可调的国产自主化研制。为了使三平台作业装置实际运行速度与调速电位器电阻之间呈线性关系,对比例电磁阀的输出电流与液压流量关系的非线性曲线进行分段处理和理论误差计算;并采用启停缓冲和启动脉冲控制策略,减小了三平台作业装置二阶系统响应的启动超调量衰减时间。仿真与实验结果表明,自主化研制的三平台作业装置实际运行性能良好,调速误差在5%以内,满足工程使用要求。
Abstract:
In view of the defect that the existing imported three-platform operation device of DPT catenary overhaul vehicle can only operate at constant speed, it adopted PWM control technology to develop a domestic self-developed system with adjustable operation speed. In order to establish the linear relationship between the actual operating speed of the three-platform operation device and the speed regulator potentiometer, non-linear relationship between the output current of proportional solenoid valve and the hydraulic flow rate is processed in segments and the theoretical error is calculated. The start-stop buffer and start-up pulse control strategy are adopted to alleviate the start-up overshoot attenuation time of the second-order system response of the three-platform operation device. The simulation and experiment results show that the self-developed three-platform operation device has good performance in field operation, and the speed regulation error is less than 5%, which meets the engineering application requirements.
