车辆钢板弹簧的机械性能,受材料及工艺方面许多细节综合的影响。例如,在制造过程中弹簧钢一般要经加热成形和热处理,随后经喷丸和预压缩等机械加工。每个步骤都能显著影响材料的组织、性能以及表层中残余应力的分布。从设计上来说,重要的是对各种加工程序要有能预先估计它的疲劳性 The mechanical properties of a vehicle leaf spring are influenced by many details of material and workmanship. For example, spring steel is generally subjected to thermoforming and heat treatment during the manufacturing process, followed by machining by shot peening and pre-compression. Each step can significantly affect the material’s microstructure, properties, and distribution of residual stress in the skin. From the design point of view, it is important to have a variety of processing procedures can be estimated in advance its fatigue
