The Dynamic Behavior and Stability Analysis of an Electro-Hydromechanical Adaptive Transmission

摘要

In the present paper is presented a numerical simulation of an electro-hydro-mechanical system of adaptive transmission of mechanical power. This system is based on a hydraulic circuit consists of a hydraulic pump with constant flow and a hydraulic motor with variable flow ordered so that the pressure in the circuit to remain constant. For a variation of the ramp and step signal sources of loads, are presented the main features of operation of adaptive transmission. Analysis of dynamic stability of mechanical transmission is made through the linear analysis with Bode diagrams. Simulation of transmission operation is performed with AMESim.
