A new coupled multi-domain computer simulation model able of predicting axial piston hydraulic pump or motor performance is presented in this paper. The model is composed of different modules, each addressing different problems associated with the machine’s operation. A lumped parameter module calculates the instantaneous displacement chamber pressure. The second and major part of the model is dedicated to the lubrication of the three main pump sliding interfaces and considers the impact of elasto-hydrodynamic, thermal, and micro-motion effects on fluid film thickness. The final sub-model calculates the steady state temperature of the fluid in the pump housing and outlet port. Simulation results are compared to measurements taken of a commercially manufactured pump.
