| Abstract: | In order to improve the ride comfort of a multi - axle off - road vehicle, a six-degrees of freedom dynamic model for an 8 × 8 off - road vehicle is built to solve the transfer functions of the road input of its first axle. The objective function is established to improve the ride comfort and the genetic algorithm is used for the matching optimization of stiffness and damping among each axle. The comparison of results before and after the improvement shows that the suspension with optimized parameters can effectively improve the ride comfort of the vehicle. |
