摘　　要：为实现铝合金车轮轻量化,用Undercut减质量结构车轮制造工艺,以483 mm(19 inch)Undercut结构车轮为例,通过热处理、机加工及旋压工艺强化Undercut结构车轮的刚性和强度。通过车轮可靠性试验及弯曲仿真试验,验证车轮静刚性、应变及疲劳寿命。结果表明:Undercut结构车轮满足300万次车轮弯曲疲劳寿命要求;Undercut结构d_(2)>6.9 mm时,安全裕度稍差,所以d_(2)>6.9 mm,可保证Undercut结构车轮静刚性要求。Undercut结构车轮研究技术可推广至其它类型及尺寸车轮的优化设计。The manufacturing process of Undercut structure was adopted to realize the lightweight of aluminum alloy wheel.The 483 mm(19 inch)Undercut structure wheel was taken as an research object.The rigidity and strength of Undercut structure wheel were improved through heat treatment,machining and spinning strengthening process.The static rigidity,strain and fatigue life of the wheel were verified by reliability test and bending simulation test.The results show that the wheel with Undercut structure meets the requirements of 3 million bending fatigue life of three million cycles.Because the safety margin is slightly poor when the d_(2) value of Undercut structure is 6.9 mm,to ensure the static rigidity requirements of wheels with Undercut structure the d_(2) value should be greater than 6.9 mm.The research technical route on the manufacturing process of wheel with Undercut structure can be extended to the optimal design of other types and sizes of wheels.
