本文提出了箱形伸缩式吊臂优化设计的一种新算法——满约束优化方法。通过对各设计参数和约束条件的分析,适当地选择设计变量,使设计变量维数得到降低。论证了达到最优点的条件,编制了吊臂优化设计程序,其迭代方向由约束状态的判断决定,所选择的变量对迭代完全是单调变化,当迭代点由容许集外进到容许集时,便可作为最优点停机。算法结构简单,且迅速有效,并将该程序用于QY45型轮式起重机吊臂的优化设计中,取得了良好的效果。
In this paper, a new algorithm for optimization design of box telescopic boom - full constraint optimization method is proposed. Through the analysis of the design parameters and constraints, the appropriate choice of design variables, design variables to reduce the number of dimensions. The conditions for reaching the optimal point are demonstrated, and the optimization design program of boom is developed. The iteration direction is determined by the constraint state. The selected variables are completely monotonous changes to the iteration. When the iteration point is outside the allowed set, It can be the best point downtime. The algorithm has the advantages of simple structure, rapid and effective, and the program is used in the optimization design of the crane arm of QY45 type wheeled crane and achieved good results.
