| Abstract: | Be based on the existing model of braking force in China, the technology to implement the simulation program of braking force was presented in this paper. The iteration method changing the stiffness of the model was used to process the first kind of inflexion question of the model and the finite dement method was used to solve the equation of braking reaction. Therefore, the time-history which can be applied in engineering application has been obtained. |
