Open-loop dynamic performance of a servo-valve controlled motor transmission system with pump loading using steady-state characteristics

This article presents a study on dynamic performance of a servo-valve controlled axial piston motor used in a transmission system. The modeling of the system has been made using bondgraph simulation technique. The various loss coefficients of the motor have been determined from the steady-state pressure/flow relationships. The simulation results obtained at different operating conditions are validated experimentally. Using the validated model, transient response of the system have been predicted with respect to the variation of some critical parameters of the system.
