摘　　要：阀控液压激振系统能耗较高,无阀激振系统在高频加载等方面尚存在不足。为解决以上问题,提出了通过配流盘连续旋转直接输出交变液流,驱动作动元件完成激振加载的泵控液压激振新方法。针对交变配流原理,设计了交变配流泵机械结构,研究了交变配流泵的工作原理,建立了交变配流泵的数学模型,分析了泵主要组成部件的结构参数和运动参数对交变流量的幅值和频率的影响规律。研究表明,配流盘连续旋转的交变配流泵能够产生准正弦交变液流,满足液压激振加载的需求。The valve-controlled excitation system commonly used in hydraulic excitation has high energy consumption,and the valveless excitation system has some shortcomings in high frequency excitation loading.In order to solve the above problems,a new pump-controlled hydraulic excitation system is proposed,which directly outputs alternating flow through the continuous rotation of a valve plate to drive the actuating elements to complete the excitation loading.Based on the principle of alternating flow distribution,the mechanical structure of the alternating flow distribution pump is designed,the working principle of the alternating flow distribution pump is studied,the mathematical model of the alternating flow distributing pump is established,and the influence of structural parameters and motion parameters on main components of the pump on the amplitude and frequency of the alternating liquid flow is analyzed.The research shows that the alternating distribution pump with continuous rotating valve plate can generate quasi-sinusoidal alternating flow to support hydraulic excitation loading.
