Analysis of a hydrostatic transmission system using low speed high torque motor

In this paper, the performance of a Hydrostatic Transmission system, consisting of a pressure compensated swashplate controlled variable displacement pump and an Orbital Rotor Low Speed High Torque hydrostatic motor has been analysed. Bondgraph modelling technique has been used to study the dynamics of the system. While modelling, the steady state solution of the motor, considered as an input, has been termed as Quasi-static solution. The effect of some critical parameters on the overall performance of the system have been investigated. Using system equations derived from the bondgraph model, the steady state behaviour of the system has been predicted. (C) 2000 Elsevier Science Ltd. All rights reserved.
