摘要
主要研究蜂窝板热管区域局部平面度超差的原因及控制方法。经分析,蜂窝叠块的尺寸精度以及胶膜固化后的厚度不均匀性是导致超差的主要原因,通过提高工装均压板的厚度,利用胶膜厚度的自适应性弥补零部件尺寸累积偏差,提高平面度,并对新方法下产品剥离、剪切强度进行测试,结果表明,该工艺方法可以在不影响产品力学性能的前提下大幅改善产品热管区域平面度。
Apparatus losing heat by fitting with heat pipe embedded in honeycomb sandwich panel. This article aimed to analyze the factors affecting the heat pipe area flatness in honeycomb sandwich panel. The dimensional preci- sion of honeycomb core and the uneven thickness of adhesive film panel after curing are the main causes. The main solution carried out is increasing the thickness of average pressure tooling board, which can compensate the parts＇ cu- mulative dimensional deviation by adhesive film. The results showed that method could be applied to practical produc- tion.
