Abstract

Short suspension system has an indispensable effect on vehicle handling and ride, so, optimization of vehicle suspension system is one of the most effective methods, which could considerably enhance the vehicle stability and controllability. Motion control, stability maintenance and ride comfort improvement are fundamental issues in design of suspension system of off-road vehicles. In this work, a dependent suspension system mostly used in off-road vehicles is modeled using Trucksim software. Then, geometric parameters of suspension system are optimized using integrated anti-roll bar and coiling spring in a way that ride comfort, handling and stability of vehicle are improved. The simulation results of suspension system and variations of geometric parameters due to road roughness and different steering angles are presented in Trucksim and effects of optimization of suspension system during various driving maneuvers in both optimized and un-optimized conditions are compared. The simulation results indicate that the type of suspension system and geometric parameters have significant effect on vehicle performance.

摘要

短悬架系统对车辆操纵和行驶有重要的影响, 因此优化车辆悬架系统是提高车辆稳定性和操纵性的有效方法之一。 运动控制、 稳定性维护和平顺性改善是越野车悬架系统设计中的基本问题。 基于 Trucksim 软件, 建立了一种主要应用于越野车的依赖悬架系统。 然后, 利用综合防摇杆和卷取弹簧对悬架系统的几何参数进行优化, 提高了车辆的平顺性、 操纵性和稳定性。 Trucksim 提供了悬架系统的仿真结果和由于路面粗糙度和转向角不同而引起的几何参数的变化, 并比较了在优化和非优化条件下, 悬架系统在各种驾驶操纵中的优化效果。 仿真结果表明, 悬架系统类型和几何参数对车辆性能有显著影响。
