摘　　要：减振弹簧广泛用于各种机械装置中,为了实现弹簧轻量化设计以及提高其寿命,应用MATLAB软件对其进行数学建模,并采用统一目标函数法通过简单编程调用MATLAB优化函数对弹簧质量和疲劳安全系数进行多目标优化设计。结果表明:优化后的弹簧质量轻,使用寿命长,并且该法简单易用,为设计人员提供了一种有效的设计手段。Shock absorber spring is widely used in mechanism sets. For decreasing spring＇ s mass and increasing the life of fatigue, by using the unified objective function method, the software of MATLAB is applied to build the numeric model of spring and the multi-objective optimization design of the mass and fatigue safety coefficient through simply programming to run the optimization function of MATLAB. The results show the mass decreases and the life increases through optimization design. Furthermore, the method is an efficient tool for the designer because it is simple and easy.
