例句与用法 | 1. | Taking the contact stress , bend stress stiffness and temperature stress as the condition , taking the weight of the kiln tyre as optimization aim function , the redia and the width of the tyre are optimized general optimize methods just consider the affecting of the parameters to aim function , but in fact , structural parameters ( such as structure dimension , interval and so on ) , physics and dynamics ( damp factor , conduct factor , friction factor material ' s elastic module strength limits and so on ) , which would be changed after used . the difference are called discrepancy robust design ' s basic concept is : all design parameters " discrepancy will affect the aim funct ion and arouse the quality target discrepancy
一般的优化方法，仅仅考虑了参数对其目标函数的影响，而实际情况下有些参数是变化的，产品的结构参数（如几何尺寸、间隙等） 、物理和力学参数如阻尼系数、传导系数、磨擦系数、材料的弹性模量和强度极限等的设计值与制造后和使用中的实际值会有差异，这种差异称为设计变量和噪声因素的变差。
