摘要
本文提出最佳容差设计方法,该方法在设计中采用初始目标函数和准中心目标函数,使设计时间缩短;在优化中采用正交优化方法,使方法简单、直观;运用求可行域最大内切球半径和球心的方法,同时确定设计元件中心值和容差;为达到最佳设计之目的,本方法在最后进行一次中心值和容差的综合设计,本文给出例证,说明此方法可行,且有优越性。
An optimal tolerance design method is presented. The method uses an initial objective function in the design process, and a close-center objective function for reducing the design time. The orthogonal array optimization method is used in order to simplify the method. The center values and tolerances of design parameters can be determined simultaneously by searching out the radius and center of the biggest inscribed globe. Finally, it is necessary to design center value and tolerance synthetically for reaching the aim of optimal design. Two examples are presented to illustrate that the method is feasible and has superiority.
