摘要: |
采用响应面法对螺栓法兰连接进行优化设计时,考虑到经典响应面模型的局限性,在获得结构优化参数与响应指标内在联系的基础上,提出了修正响应面模型;设计了数值试验并对比了数值试验值与前述两种响应面模型预测值,结果表明修正响应面模型的预测值不仅误差相对比较均匀,且最大误差绝对值要明显小于经典响应面模型的相应值。采用遗传算法对修正响应面模型进行了以法兰质量最轻为优化目标的参数优化,取得了比较理想的优化结果。 |

Abstract: |
In consideration of the limitation of TRSM (typical response surface method), a MRSM (modified response surface method) which was based on the inner connection between optimization parameters and appointed response was put forward. Several numerical experiments were conducted, and the results were compared with the predicted values of both models. The comparative results show that the MRSM′s predicted values are more uniform than TRSM′s and the max error absolute value is smaller than TRSM′s. By using genetic algorithm, the MRSM is optimized whose aim is to minimize the weight of flange and an ideal result is obtained. |
