摘　　要：提出了确定门机对重质量及其位置的动态优化法。其基本思想是 :计及惯性力和风力等影响 ,在满足结构布置等要求的前提下 ,以变幅电机功率最小为目标函数 ,建立非线性约束优化的数学模型 ,并用正交计算法求解 。The dynamic optimization method of determining the counterweight and its center of portal crane is put forward.The basic thought is to take the minimum luff motor power as object function and to establish optimized non linear limit mathematic model considering the influence of wind and inertia force.Good results are achieved by program calculation.
