The Optimal Design for Tight Joints of Ordinary Bolts

本文对约束正负项式几何规划对偶法的数学模型、原规划问题和对偶规划问题之间的关系和算法步骤作了简要介绍。并用该法对液压油缸的普通螺栓组紧联接进行了优化设计。结果表明:该法运算简便,不用计算机,而且可求得问题的全域最优解。

The mathematical model of the constrained positive ?negative term geometrical programming duality method,the relationship between the original and the duality programming,and the algorithmic steps are briefly reviewed. The method is employed for the optimal design for tight joints of ordinary bolt set on a hydraulic cylinder. The results show that this method is simple in calculation,no computer is needed and the optimized solution over the closed region can be obtained.
