Hydro-mechanical variable transmission system （HMCVT） is a new kind of transmission system. It is valuable to study this kind of transmission. The Multi-disciplinary virtual prototype of HMCVT was modeled. The dynamic response characteristic of the HMCVT influenced by parameters changing of hydraulic components was analyzed based on the multi-disciplinary virtual proto- type of HMCVT. The simulation results provide reference for the establishment of control strategy and application of the HMCVT system.
