脱胶缺陷尺寸对塑料内胆纤维缠绕气瓶传热影响及显著性分析
Influence and significance analysis of degumming defect size on heat transfer of plastic liner fiber wound gas cylinder
摘要
Abstract
In order to solve the heat transfer problem of wound gas cylinder with degumming defect plastic inner liner fiber under thermal excitation,numerical simulation and infrared detection test methods were used to study the effect of different sizes of degumming defect in wound layer on the heat transfer of gas cylinder,and the significance of size parameters of degumming defect was analyzed by significance analysis.The results show that the order of the delamination defect size parameter on the maximum temperature difference of the outer surface of the gas cylinder is the length of the defect﹥the depth of the defect﹥the height of the defect itself.The F value of the degumming defect length is 5 521.5,which is far greater than the 9.3 of the height of the defect and 11.9 of the defect depth.The results can provide reference for the quantitative study of infrared detection of degumming defect in plastic inner liner fiber wound gas cylinders.关键词
