摘要:

 为探究不同冲制工艺方案对栅元管成形质量的影响,以减薄率和回弹量作为评价指标,建立了“先胀后压”和“先压后胀”两种有限元冲制模型,并通过拉丁超立方抽样得到128组不同工艺参数下的减薄率和回弹量数据样本。利用贝叶斯优化算法-多层感知机(BOAMLP)进行成形质量预测,将预测模型导入到多目标优化算法NSGAⅡ中,求得两种冲制方案下的Pareto最优前沿解,并采用灰色关联度分析方法,计算不同工艺参数对成形质量的灰色关联度系数。结果表明:建立的两种冲制模型均能够较为准确地预测栅元管的成形质量,综合考虑回弹量和减薄率因素,“先压后胀”方案得到的栅元管的成形性能更优,有助于指导栅元管的冲制加工。

 In order to explore the influence of different punching process schemes on the forming quality of grid tube, taking the thinning rate and springback amount as the evaluation indexes, two finite element punching models of “expanding before pressing” and “pressing before expanding” were established, and 128 sets of data samples of thinning rate and springback amount under different process parameters were obtained by Latin hypercube sampling. Then, the forming quality was predicted by BOA-MLP algorithm, and the prediction model was introduced into the multi-objective optimization algorithm (NSGA-Ⅱ) to obtain the Pareto optimal frontier solution under the two punching schemes. Furthermore, the gay correlation degree of different process parameters on the forming quality were calculated by using the grey correlation analysis method. The results show that the two kinds of punching model can predict the forming quality of the grid tube accurately. Comprehensive consideration of springback amount and thinning rate, the forming performance of grid tube by“pressing before expanding” scheme is better, which is helpful to guide the punching process of the grid tube.
