| 摘 要： | 为实现车辆操控的方便性,以履带车辆纯机械液压变量系统为基础,提出一种新型无线遥控电液伺服变量控制系统。基于无线传输易被干扰出现乱码的情况,设计了无线遥控指令信号的生成方法,介绍了硬件电路和电液伺服系统的原理及组成。考虑到无人驾驶对液压系统响应的快速性要求,以提高电液伺服系统的响应速度,在AMESim中完成对液压伺服系统建模,分析了活塞和高频响比例伺服阀结构参数对电液伺服系统响应速度的影响,找到了提高响应快速性的几个重要影响因素,为无线遥控变量液压系统设计奠定了理论基础。实验证明方案可以实现无线遥控的功能。

| Abstract: | In order to improve convenience of tracked vehicle control, a new type of wireless electro-hydraulic servo steering control system is proposed based on mechanical hydraulic steering system of tracked vehicle. Because wireless transmission is easily disturbed and generates random code, a method of steering command signal for wireless remote control is designed. The principle and composition of hardware circuit and electro-hydraulic servo system are introduced. Considering rapid response of unmanned driving to hydraulic steering system, in order to improve response speed of electro-hydraulic servo system, a hydraulic servo system is modeled in AMESim, and the influence of structure parameter of the piston and high frequency proportional directional valve on the response speed of electro-hydraulic servo system is analyzed. Several important factors affecting the rapidity of response are found, which establishes a theoretical foundation for the design of wireless control steering hydraulic system. The experiment proves that the scheme can realize the function of wireless control. |
