| 中文摘要: |
| 使用自主研发的通用优化设计软件系统SiPESC.OPT,基于某型号机械压力机结构参数,构建机械压力机六连杆机构动力学优化模型．采用随机优化算法-梯度优化算法相结合的方法,使用GA、SQP和SLP多种算法组合优化计算．与初始设计相比较,优化后机械压力机的锻冲阶段滑块最大速度、行程速比系数等工作性能指标均有所改善． |
| 英文摘要: |
| Based on a practical mechanical press structural parameters, a dynamics optimization model of six-bar linkage is optimized by SiPESC.OPT, which is independently-developed optimization software for general purpose. A combined stochastic-gradient optimization method, combining genetic algorithm (GA) with sequential quadratic programming (SQP) algorithm and sequential linear programming (SLP) algorithm, is utilized for optimization calculation. The performance measures of the mechanical press, maximum speed of forging process and advance-to-return ratio, are improved. |
