摘要
相较于普通子午线轮胎,非充气轮胎具有较好的防爆性能,但在减振性、舒适性及操控性等方面存在一定的劣势。以降低轮胎簧下质量为优化目的,基于Tweel非充气轮胎,以单块辐板为研究对象,利用有限元分析法进行结构优化设计与性能研究。首先通过辐板载荷工况下应力分布情况确定辐板中间部位为优化位置,并且基于蜂窝六边形设计了多孔辐板结构,研究不同基孔数量和排布方式下的优化方案对轮胎性能的影响。研究结果表明:轮胎的下沉量、最大应力与基孔数量呈负相关,通过对比发现,辐板3排基孔数量为16时,适当地增加辐板厚度,非充气轮胎性能更接近于未优化无孔结构轮胎。研究结果可为非充气轮胎结构的优化提供理论指导。
Compared with normal radial tires, non-pneumatic tire has better explosion-proof performance, but it has certain disadvantages in vibration damping, comfort and controllability. In this paper, the optimization purpose is to reduce the unsprung mass of tire. Based on non-inflatable tire of Tweel, the finite element analysis is used to optimize the structure design and study the performance of a single spoke plate. Firstly, according to the stress distribution of the spoke under the load condition, the middle part of the spoke is determined as the optimization position. The porous structure is designed based on the honeycomb hexagon, and then study the influence of the optimization scheme on the tire performance under different number and arrangement of base holes. The results show that the displacement and maximum stress of the tire are negatively correlated with the number of base holes. By comparison, it is found that when the number of base holes in three rows is 16, the performance of the non-aerated tire is closer to that of the unoptimized tire when the thickness of the spoke is increased appropriately. The research results provide theoretical guidance for the optimization of non-aerated tire structure.
