摘要
研制了一套采用电液比例溢流阀的液压加载系统,对试验机进行试验载荷加载。通过对电液比例系统输入不同的控制信号,模拟不同的试验工况。给出了系统的数学模型,并分析其闭环反馈控制系统的实现形式。
A kind of hydraulic loading system,with an electro-hydraulic proportional pressure valve as its core component is presented,aimed to support load to the test machine.The system could simulate different work conditions by giving different signals to the electro-hydraulic system.The math model of the system is illustrated.Meanwhile,the analysis of realization of the feedback control system is fulfilled.
