摘　　要：为了提高激振器位置控制精度和降低成本设计了具有位置反馈的激振器,只需要利用激振换向阀和振动活塞位置信息反馈结果便能够实现活塞的自动换向,可以在一个较宽的区间调控激振频率与活塞行程.基于AMESim平台开展仿真分析,并对关键参数进行优化.研究结果表明:逐渐提高系统流量的过程中,活塞达到了50 Hz的最大激振频率,活塞冲程和系统激振能都发生明显升高.提高激振器压力后,获得了53 Hz的最大激振器频率,激振器活塞行程与活塞动作仿真测试结果相符.当活塞反馈孔间距增加后,激振器达到了更大的活塞动作行程,表现为线性增长.反馈孔间距达到25 mm以上时,获得了相对稳定的冲程末速度.In order to improve the position control accuracy and reduce the cost of the shaker,a hydraulic shaker with position feedback is designed.The automatic reversing of the piston can be realized only by using the feedback results of the exciting reversing valve and the position information of the vibrating piston,and the vibration frequency and piston stroke can be controlled in a wide range.Simulation analysis is carried out based on AMESim platform,and the key parameters are optimized.The results show that the piston reaches the maximum excitation frequency of 50 Hz during the process of increasing the system flow rate.The piston stroke and excitation energy of the system have increased obviously.After increasing the shaker pressure,the maximum shaker frequency of 53 Hz is obtained.The piston stroke of the shaker agrees with the simulation test results of piston action.As the distance between piston feedback holes increases,the shaker reaches a larger piston stroke,showing a linear increase.When the feedback hole spacing reaches more than 25 mm,a relatively stable end stroke velocity is obtained.
