摘要
为了提高飞机机体损伤应急快速胶接修理的质量和效率,利用弹塑性有限元分析及试验方法探讨了胶接修补飞机蒙皮时补板厚度对胶接补强水平的影响。发现合理选取补板厚度可明显提高胶接修补的补强水平,进而提高修复结构的强度,一般情况下,取补板厚度小于蒙皮板厚度。这一新的胶接修补技术在不改变原有的修补工艺、材料、设备的前提下,可提高胶接修理的水平、机体结构的强度,减轻飞机结构质量,简化操作,降低成本。
In order to enhance qualities and efficiency of rapid- bond- repairing of damaged aircraft body, this paper probed into the effect of thickness of patch plate on strengthening level of bonding in repairing damaged aircraft skin via plasto-elastic finite-element analysis and experiments, and discovered that rationally choosing the thickness of patch plate can remarkably increase the strengthening level of bonding and the strength of the repaired structure. Generally, the thickness of patch plate should be less than that of not damaged aircraft skin. This new bond-repairing technique created by the above analysis can increase the strengthening level of bond repairing and the strength of the repaired structures, predigest the operation and decrease the weight of the repaired structures and the cost of repairing on the condition of not changing formal technique, materials and apparatus.
