摘要：
To improve the rationality of dynamic power matching between skid-steer loader engine and hydraulic system, the power characteristics of the traveling hydraulic system of skid-steer loader were studied, and taking a certain model of skid-steer loader as an example, the theoretical model of power characteristics was established. AMESim software and Virtual Lab Motion multi-body dynamics software were used to establish the corresponding joint simulation model, and the power characteristics of the traveling hydraulic system of the skid-steer loader under typical working conditions were simulated and analyzed. The accuracy of the simulation model was verified through experiments. The results show that with the decrease of steering radius, the output power of the traveling system of skid-steer loader increases gradually; the traveling system consumes less power when skid-steer loader runs straight; there is parasitic power in the inner steering wheel when the vehicle is of unilateral steering; the power consumption of the traveling system is larger when the vehicle is of bilateral steering. © 2020, Central South University Press.
