摘要

为了能够切实有效地对机械压力机杆系驱动机构进行优化设计

采用响应面分析法并结合试验设计方法

提出了求解该杆系多目标优化问题的变量循序组合响应面法(VSCRSM)

并建立了优化数学模型.对优化变量及其变化范围进行循序取舍组合和设定

同时采用响应面分析法多次拟合进行优化求解

最终得到了优化结果.与初始设计及变容差遗传算法相比较

VSCRSM优化目标的最小值分别降低了15.85%和5.8%

并且滑块行程误差仅为0.09%

不仅解决了初始设计及变容差遗传算法所得结果中滑块行程超出误差范围的问题

而且实现了压力机杆系的显著优化.

Abstract

To realize a practical and effective optimum design of rod system in double toggle mechanical press

variable sequential combination response surface methodology(VSCRSM)is proposed to solve the multiple objective optimization

then the mathematic models are established. The optimal design variables and their ranges are sequentially combined and set

and response surface methodology is repeatedly employed. The optimization results show that VSCRSM enables to decrease the minimum of the objective function by 15.85%

compared with the initial design

and by 5.8%

compared with the flexible tolerance genetic algorithm. VSCRSM confines the error of the slider stroke as 0.09%

thus the problem is solved that the error is beyond limited range in the initial design and the flexible tolerance genetic algorithm.
