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 of generalized momentums of inertia and the generalized displacements of volumetric elements as the state variables, the state equations of the system are deduced. Based on the 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 result of analysis illustrates that the HMT system needs less than 0.5 s to attain the steady state in its dynamic response and takes longer when the fluid volume is increased.
