| Abstract: | A mathematical model of the multi-range hydro-mechanical continuously variable transmission(HMCVT) is presented for the development of its control system.The mathematic model for HMCVT dynamic transmission system and auto-controlling system is established by means of dynamic principle and modular method.Matlab software is used to carry out the simulation of the process of infinitely varable speeds and range shift control,and the method of setting global variables is used to avoid the occurrence of the abnormal solution in simulation.The simulation results indicate that this model is able to express HMCVT dynamic characteristics effectively and also can be used as the software simulation to develop the infinitely varable speeds control algorithm and the foundation for hardware simulation. |
