牵引车空气悬架结构件轻量化设计

Lightweight Design of Air Suspension Structure of a Tractor

为实现牵引车空气悬架结构件的轻量化并验证其强度性能,首先运用CATIA对牵引车空气悬架系统进行了轻量化设计,然后建立空气悬架结构件有限元模型,最后在不同工况条件下对部分结构件新旧材料和结构的轻量化做了对比仿真分析。结果表明,优化后的模型最大Von-Mises应力均小于旧材料,强度性能仍能满足使用要求,并且重量均减轻,达到了轻量化的效果,符合设计要求。此设计提高了运输效率,降低了油耗以及全生命周期运营成本。

In order to reduce the weight of the air suspension structure of the tractor and verify its strength performance,CATIA was first used to design the lightweight of air suspension system of the tractor,then the finite element model of the air suspension structure was established,and finally a comparative simulation analysis was made on the new and old materials and lightweight structure of some structural parts under different working conditions.The results show that the maximum Von-Mises stress of the optimized model is less than that of the old material.The strength performance can still meet the requirements of use,and the weight is reduced,achieving a lightweight effect and meeting the design requirements.This design improves transportation efficiency,reduces fuel consumption and life cycle operating costs.
