某型装备保温舱铰链改造技术研究

Retrofitting Technology for a Certain Type of Thermal Insulation Shelter Hinge

目的解决某型装备保温舱通条铰链连接铆钉松脱、铰链变形、舱壁夹层渗水等问题。方法分析装备的结构特点和工作时铰链的受力情况,找出了问题产生的原因,提出改造技术措施和方案,并在此基础上开展挤压试验、开关厢盖试验、淋雨试验、650 km行驶试验等试验研究。结果结合装备整修对保温舱进行了改造,将保温舱由通条铰链改为合页铰链后,装备性能得到极大改善。结论通过改造消除了故障隐患,提高了装备的使用性能,满足部队的使用需求。

Objective To solve the problems of continuous piano hinge rivet loosening, hinge deformation, interlayer seepage, etc. of a certain type of thermal insulation shelter. Methods Structure characteristics of the equipment and stressing situation of the hinge were analyzed to find the reasons of the problems and propose technical measures. On this basis, the squeezing test, opening closing test, rain test, driving test（650 km）, etc. were performed. Results The thermal insulation shelter was retrofitted in combination with renovation of equipment. The continuous piano hinges of the thermal insulation shelter were changed to butterfly hinges. The performance of the equipment was promoted tremendously. Conclusion The retrofitting eliminates hidden troubles, improves the using performance and meets the needs of the army.
