doi:10.3901/JME.2017.14.209

Abstract

Abstract: Based on the working principle and characteristics of resonant wave generation device, the power take-off system is designed combined with the prominent advantages of hydraulic transmission in power extraction. The mathematical model of power take-off system is established, and the computer simulation is carried out by AMESim. Through the simulation test of oil supply, accumulator and proportional flow control valve, the theoretical basis for the performance optimization and power control of the system is provided. In the laboratory environment, the test platform of power take-off system is established. The reliability of the theoretical analysis and simulation results are verified by the experimental results of pressure-maintaining storage test and extraction power test. The simulation and experimental results show that oil supply can significantly improve the stability and increase the output power, and rational allocation of accumulator can effectively reduce the fluctuation of pressure and flow, and proportional flow control valve can adjust and stabilize the flow and then adjust the output power. The measures above can ensure the good dynamic and steady state characteristics which make it possible to generate steady and continuously, adjust the power quickly, shorten the transient process.
