摘要：

将稳健设计思想和优化设计思想相结合，将加工误差等因素引起的影响考虑在设计变量的容差之中，寻求弹簧刚度系数误差最小化，且以弹簧结构参数在其容差内变化时弹簧刚度系数的最大波动量的最小化为优化目标，建立了具有多目标、两级优化的分闸弹簧稳健优化设计数学模型。提出了系列求解该数学模型的优化策略。将稳健优化设计数学模型应用于10kV、12.5kA真空断路器弹簧操动机构中的分闸弹簧的设计，有效改善了分闸弹簧的力特性及真空断路器的分合闸速度特性。

Abstract:

A design for breaking spring of a spring actuator of vacuum circuit breaker based on robust optimization was presented. The effects of some factors, shch as processing errors,were come down to the tolerance of the design variables.In order to minimize the error of spring stiffness coefficient,the maximal variation of stiffness coefficients when the design variables varied within the acceptable region of the

tolerances were chosen as the objective function.So a robust optimization mathematical model of the breaking spring was given.A series of optimization strategy were presented. Applying the above theory to the structure design of the breaking spring of

spring actuator of 10kV,12.5kA vacuum circuit breaker, the breaking and closing characteristics are all satisfied at the optimum structure parameters. 

Key words: spring actuator, breaking spring, stiffness coefficient, robustness, optimization
