地铁头车半自动钩缓装置试验台检测钩头最大水平摆角的联挂状态时,需要液压马达带动装有车钩的可调支座横向移动一定距离以使达到预期的摆角。对阀控马达电液位置伺服控制系统的频率特性、稳定性、控制误差等作了分析,并对DYC1伺服阀进行了详细的建模。通过AMEsim/Simulink的联合仿真分析,同时采用模糊策略优化控制效果,所设计的液压系统准确、稳定、可靠,车钩摆角完全达到预期要求的效果。随着工程对象的复杂化,AMEsim/Simulink联合仿真这方法为解决复杂工程控制难题、液压元件的设计等开创了一条效果很好的途径。
Subway head car semi-automatic hook and loop device test bench to detect the maximum horizontal hook angle hanging state, the need for hydraulic motor driven coupler equipped with adjustable lateral bearing a certain distance to achieve the desired swing angle. The frequency characteristics, stability and control error of valve-controlled electro-hydraulic position servo control system are analyzed. The DYC1 servo valve is modeled in detail. Through the AMEsim / Simulink joint simulation analysis, the fuzzy strategy is used to optimize the control effect. The designed hydraulic system is accurate, stable and reliable, and the swing angle of the coupler fully meets the expected requirements. With the complexity of engineering objects, this method of AMEsim / Simulink co-simulation has created a very effective way to solve the complex engineering control problems and the design of hydraulic components.
