汽车横向稳定杆系统优化设计

Optimization Design of Suspension Stabilizer Bar System for Vehicle

横向稳定杆系统是汽车悬架中的一种重要辅助弹性元件,在改善汽车平顺性方面可以提高汽车的侧倾刚度,减少汽车横向侧倾程度。基于此目的,在满足汽车安全可靠的基础上,对汽车横向稳定杆系统进行了合理的悬架系统刚度匹配及轻量化设计,最后通过对优化后汽车前后横向稳定杆系统的ANSYS疲劳寿命校核,结果表明汽车的操纵稳定性通过优化得到显著提升。

Suspension stabilizer bar system is an important elastic aid element,which can improve the car's roll stiffness,reduce racing lateral roll and improve ride comfort level.On the basis of satisfying contest safety and reliability,the stiffness of suspension system was matched reasonably,lightweight optimization design was completed for suspension stabilizer bar system,fatigue life verification was simulated and analyzed using ANSYS.The results show that the handling stability was effectively improved through optimization design for suspension stabilizer bar system of vehicle.
