介绍了后置式俯仰机构的优化设计,在作图法完成后支撑方式初步设计的基础上,以电动缸驱动力与近似功率的加权函数最小为优化目标,考虑各类约束,建立了真实性较高的数学模型,并选择复合形法在MATLAB中编写优化程序进行优化求解,得到了后支撑方式下最优的举升机构铰点位置布局方案。
介紹瞭後置式俯仰機構的優化設計,在作圖法完成後支撐方式初步設計的基礎上,以電動缸驅動力與近似功率的加權函數最小為優化目標,攷慮各類約束,建立瞭真實性較高的數學模型,併選擇複閤形法在MATLAB中編寫優化程序進行優化求解,得到瞭後支撐方式下最優的舉升機構鉸點位置佈跼方案。

This paper introduces the layouf optimized design, it based on the preliminary support design. The optimization target is the weighted function of electric cylinder driving force and its approximation power, considering all kinds of con-straints, the mathematical model was established. The optimization program was wrote in MATLAB with complex method. The correctness of the optimization method is verified through the virtual prototype dynamics simulation.
