The Simulation Study of Vehicle Hydro-Mechanicai Continuously Variable Transmission Test Based on AVL CRUISE

Abstract

Hydro-Mechanicai continuously variable transmission (HMCVT) performance test simulation method is proposed. Establish HMCVT test simulation model using AVL CURISE of the forward simulation software and design of HMCVT loading control strategy using SIMULINK based on the analysis of HMCVT performance and its test principle, Through the INTERFACE communication model and the control strategy, The transient simulation of HMCVT three working modes of loading. Transient loading of HMCVT simulation system for the transient response of HMCVT is satisfied and given the assessment for the speed characteristic and efficiency characteristic of HMCVT. The results show that the simulation testing of the HMCVT performance tests based on AVL CURISE, There is a transient characteristic and speed characteristic, efficiency characteristic is superior to the traditional transmission, Has a certain application value for the development of HMCVT dynamic test system.
