| Abstract: | To establish working process simulation model of a single piston hydraulic free-piston engine,its basic feature is presented.Based on the theories of thermodynamics,hydromechanics and dynamics,its mathematical representations for the steady state working process are investigated.The simulation results are verified experimentally.The results show that the mathematical model considered the mechanical components dynamics of the hydraulic system achieves high precision.The simulated piston dynamics,cylinder gas... |
