为评估材料制造弹簧的性能,研究了琴钢丝、油淬火钢丝和奥氏体不锈钢丝等弹簧钢丝。研究中量化弹簧性能参数:(1)加工问题;(2 )极限应力;(3)松弛性能;(4)疲劳性能。1 试验材料试验钢丝的规格和化学成分见表1。(1) 2种琴钢丝。试验钢丝比BS 5 2 16M5 (当前国际技术规范中强度最
In order to evaluate the material properties of the spring, spring steel wires such as piano wire, oil quenched wire and austenitic stainless steel wire were studied. Quantitative spring performance parameters studied in the study: (1) processing problems; (2) ultimate stress; (3) relaxation performance; (4) fatigue performance. 1 Test Materials Test wire specifications and chemical composition in Table 1. (1) 2 kinds of piano wire. Test wire ratio BS 5 2 16M5 (currently the most stringent international technical specifications
