Dynamic Simulation of Hydro-mechanical Differential Turning Hydraulic System of Tracked Vehicle

摘要

Being an important subsystem of hydro-mechanical differential turning system of tracked vehicle, the turning hydraulic system plays the crucial role on turning and running performance of tracked vehicle. The mathematical model and simulated model of turning hydraulic system are established. The dynamic performance of different running parameters and structural parameters of certain tracked vehicle is simulated and analyzed adopting Runge-Kutta four, five step arithmetic in this paper. The theory basis of system optimization design, parameters match and performance analysis of hydro-mechanical differential turning system is provided.
