  • 611 Estimation of Dynamic Forces between 4 Wheels and Road using Multi-body Dynamics Suspension Model

抄録

This paper proposes a estimation method of dynamic forces between 4 wheels and road using strain information of steering nuckle. First, we propose a vehicle-tyre model. It contains nonlinear caracteristics of tyre by Magic Formula function. In addition, we design multi-body dynamics suspension model. And we conduct the coupled simulation to obtain the boundary condition of steering nuckle. Then, in order to decide the optimum positions of strain sensors to estimate the forces, FEM simulations are conducted.
