In this paper,the engine output torque model and fuel consumption model are established based on engine test results.The engine rotary speed feature denotes the relationship between the engine rotary speed and the throttle opening when engine works in the optimal modes of economic and power operating.On the basis of the above work,the matching strategies of hydro-mechanical continuously variable transmission (HMCVT) system are put forward.The two typical working conditions of tractor are analyzed by simulation method.The results show that the matching strategies determined in this paper are correct and feasible,and the reasonable matching of engine and HMCVT system is realized.The research provides theoretical foundation for design and control method determination of HMCVT system.
