摘要/Abstract

摘要： 采用"干长桁+湿蒙皮"共胶接工艺制造复合材料帽型加筋壁板零件时，发现长桁在胶接固化后普遍存在压塌式变形及胶接面胶层厚度不均匀的现象。为改善上述问题以实现复合材料帽型加筋壁板的高精度成型，通过试验件的制造和检测收集了长桁胶接前后的变形数据及胶接后的胶层厚度数据，分析了长桁在热压罐中胶接时的受力状态及导致长桁变形的主要原因，并采用有限元模拟对分析进行了验证。结果表明：帽型长桁在胶接后确实发生了压塌式变形，长桁胶接时帽顶R区的内外压力差及长桁缘条侧边加压不充分是导致变形的主要原因。将长桁缘条侧边倒成斜边或可减小这种变形的程度。

Abstract: When using the "dry stringer+wet skin" co-bonding process to manufacture hat stringer stiffened composite panels, the stringer hat often shows collapse deformation and uneven adhesive thickness after bonding. In order to improve the above problems and achieve high precision manufacture of the stiffened panels, the stringer de-formation data before and after bonding and the adhesive thickness data after bonding are collected through manufacture and profile and dimensional measurement of test panels. Free-body force analysis of the hat stringer during bonding is conducted to determine the main causes leading to the deformation of stringer. The analysis is verified by finite element simulation. The results show that the hat stringer does occur collapse deformation after bonding. The main causes of the deformation of the stringer are the pressure difference between inside and outside of the corner of stringer hat top and the insufficient pressure on the flange edge of stringer during bonding. Chamfering the stringer flange edge may reduce the degree of deformation.
