In order to solve the problem of rapid erection,this paper proposed a linear motor driven hydraulic pump source device for hydraulic erection system.The device consists of a linear motor and a single-stage hydraulic cylinder.The electromagnetic force was converted into a linear thrust by the linear motor,and the single-stage hydraulic cylinder was driven to output pump.The device has the advantages of small volume,large flow,high response,and easy control.This article first designed the structure of the pump source device and performance test device,and established a mathematical model.Then,it used finite element to design and optimize the linear motor.Finally,the linear motor model was established by simulink and the hydraulic circuit model established by AMESim were combined to simulate to test the performance characteristics of the pump source device.The test results show that the designed pump source device can stably output pump driving 300 kN with a flow rate of 1400 L/min and a pressure of 3.7 MPa.The load runs 2.3 m within 10 s.The conclusion in this paper provides a new reference idea for the optimization design of the pump source device in the hydraulic erection system.
