摘要
采用二次回归正交试验优化设计方法对强力旋压和热处理后的锡青铜连杆衬套性能进行了研究,得出了主要参数(减薄率、热处理温度和进给速度)对衬套性能(布氏硬度、抗拉强度、断面收缩率和弹性模量等)的影响规律,并获得了优化后的工艺参数组合和回归方程。
The performances of bronze connecting rod bushing after power spinning and heat treatment were researched by using the quadratic regression orthogonal method. The influences of the main parameters （thinning ratio, the temperature of heat treatment and feed ratio） on the bushing performance （brinell hardness, tensile strength, percentage reduction of area and elastic modulus, etc） were obtained. And the optimal combination of process parameters and the regression equation were gained.
