Abstract

The working conditions of Military off-road vehicles are harsh and complex, which put forward higher requirements on vehicle dynamic performance. Parameters of the transmission system obtained by the traditional geometric series division method is usually difficult to achieve good dynamic property and fuel economy. This paper proposed a comprehensive objective function of dynamic property and fuel economy based on weight coefficient method. On the basis of the traditional geometric series division method, considering the dynamic constraint conditions of off-road vehicles, a set of optimal transmission parameters are confirmed using the nonlinear optimization function fmincon in Matlab optimization toolbox. Simulation results show that the acceleration time and fuel consumption reduced after optimization, and the military off-road vehicles achieved a better dynamic property and fuel economy.
