波纹板夹层结构具有重量轻、刚度大和热交换性好等特点,在液体火箭发动机燃烧室和某些热交换器中获得了广泛应用。本文对波纹板夹层结构模拟试验件(简称圆筒模拟件)的试验工作做以简要介绍。本工作得到朱广敷、章业增、庹鹏等同志的大力帮助,谨表谢意。钎焊方法圆筒模拟件如图1所示,它有160多条波纹,钎焊缝总长度超过100多米,要求钎焊 Corrugated sandwich structure has the characteristics of light weight, large rigidity and good heat exchange. It has been widely used in the liquid rocket engine combustion chamber and some heat exchangers. In this paper, the corrugated board sandwich structure simulation test (referred to as cylindrical simulation) test work to do a brief introduction. This work has been greatly assisted by Zhu Guangfu, Zhang Yezeng, Peng Peng and other comrades. Brazing method Cylinder simulation shown in Figure 1, it has more than 160 ripples, brazing seam total length of more than 100 meters, requires brazing
