摘要:
基于帕斯卡原理设计了一种新型的电液力加载装置。该装置采用电动缸代替传统加载系统中的流量/比例伺服阀作为执行元件,基于密闭液体的体积变化与压力变化之间呈反比的特性,通过电动缸活塞推杆挤压承压筒产生高压,从而实现大范围、高精度的压力控制。首先,基于系统的动力学原理建立了力加载系统完整的数学模型。其次,引入串级控制思想,根据系统的动态特性逐环设计了包含电动缸速度内环及压力控制外环的多闭环PID控制器,并通过仿真分析了系统的稳定性和控制效果。最后,对某型船舶轴系实施了动态力加载试验,实验结果表明该加载装置具有良好
Abstract:
In this paper, a new electric hydraulic loading device is designed based on the Pascal's principle. The device uses the electric cylinder, instead of the flow/proportion servo valve in the traditional loading system, as the actuator. According to the characteristics of the inverse correlation between the changes of pressure and airtight liquid volume, the pressure tube is pressed by the electric cylinder piston to produce high pressure. Thus, a wide range of high-precision pressure control is achieved. In this research, firstly, the complete mathematical model of the force loading system was established based on the dynamic principle of the system. Secondly, the cascade control idea was introduced. According to the dynamic characteristics of the system, the multiple closed-loop PID controller with the electric cylinder speed inner ring and the pressure control outer ring was designed, and the stability and control effect of the system was analyzed by simulation. Finally, the dynamic loading test was carried out on a certain type of ship shaft. The experimental results show that the loading device is of good dynamic loading performance.
