Abstract

In order to study the dynamic characteristics of a hydro-mechanical transmission (HMT) system, a bond graph model of the dual-power state of flow of the two ranges HMT system is established based on the bond graph theory. Taking the elements at the state variables, the state equations of the system are deduced. Based on this model, dynamic response of the HMT system is simulated. The response characteristics of output speed and systemic pressure of the HMT are given when the load, input speed and angle of slope plate of the pump change by their respective rules, and the influence of fluid volume is analyzed. The results of analysis illustrates that the HMT system needs less than 0.5 s to attain the steady state in its dynamic response and will take longer when the fluid volume is increased.
