MODELING OF ELECTROHYDRAULIC DRIVE SYSTEM WITH AN INTEGRATED HEAT EXCHANGER IN DYNAMIC MODE

Abstract

The paper inhere describes the operation of an automated electrohydraulic drive system with a rotary actuator and an integrated "tube in tube" heat exchanger. A nonlinear mathematical model has been developed which reflects the dynamics of the system considering the alteration in temperature of the working fluid. The operation of the described automatic system is discussed in order to keep constant the temperature of the working fluid as a part of the electrohydraulic drive system. The developed mathematical model can be used for studying the dynamic processes in various system modes.
