摘要:

为确定鼓胀高度与鼓胀压力的关系,实现压力鼓胀的可控性,在分析激光焊蜂窝夹套制造工艺与特点的基础上,进行了压力鼓胀过程的应变电测实验.实验结果表明:鼓胀过程离蜂窝点越近的区域越先进入塑性变形,鼓胀高度随鼓胀压力和蜂窝点间距的增大而增大,随夹套板厚的增大而减小.此外,结合压力鼓胀实验的验证性数据,建立了菱形结构元有限元计算模型,并借助“卸载近似法”,形成了与液氨、水蒸气25%酒精水对应的各种型号夹套的鼓胀压力-鼓胀高度的优选推荐系列,对激光焊蜂窝夹套的生产制造具有参考价值.

Abstract:

In order to determine the relation between distending height and pressure and to achieve the controllability of pressure distention, strain measurement experiments on pressure distention of laser welding dimple jacket were conducted through analyzing the features of fabrication process. Experimental results indicate that the zone near honeycomb first appears plastic deformation and the distending height  increase with increasing honeycomb spacing and decrease with increasing thickness of jacket plate. Diamond structural element was determined as the finite element model and a series of preferred distending height and pressure corresponding to the jacket full of liquid ammonia or water vapour or 25% alcoholic solution respectively were proposed by combining the experimental data about pressure distention, unloading approximation method and finite element analysis, and it is  useful as guidance for the manufacture of laser welding dimple jacket.
