optimize-
键是一种标准零件,通常用来实现轴与轮毂之间的周向固定以传递转矩，有的还能实现轴上零件的轴向固定或轴向滑动导向。在键连接设计时，间的高度和宽度根据轴的直径d选取，而键长L则根据轴上零件轮毂宽度B而定，通常L=B-（5—10）mm。键的尺寸确定后，再进行强度校核。而为了保证绝对安全，键的尺寸取值往往都趋于保守，所选键的尺寸大。本程序采用优化设计方法，在满足强度要求的前提下求出键的最小结构尺寸，证明键宽b和键高h的取值可以小于标准值。(Key is a standard part, often used to achieve between shaft and hub to transfer torque to a fixed week, and some can achieve a fixed axis or axial parts of the axial sliding direction. Key connection in the design, height and width between the shaft diameter d according to selection, and the bond length L is based on the width of the wheel shaft parts B and, typically L = B-(5-10) mm. Key size is confirmed, then strength check. In order to guarantee absolute security, key size values ??are often conservative, the size of the selected key to big. The program uses optimization methods to meet the strength requirements of the derived key premise of the minimum structure size, proved key width b and height h of the key values ??can be less than the standard value.)
