摘　　要：在飞机强度地面验证试验中,载荷施加处于极为重要的环节。一种由橡胶块和铝制衬块组成的新型双向载荷施加技术,近年来在飞机结构强度验证中得到应用,提高了载荷施加精度,提升了试验效率。但作为一种新型双向载荷施加技术,其连接强度备受设计人员关注。文章旨在通过有限的试验数据,初步探究连接强度影响因子。In the aircraft strength ground verification test,the application of load is a very important link.A new bi-directional load application technology composed of rubber block and aluminum lining block has been applied in the strength verification of aircraft structure in recent years,which improves the accuracy of load application and the test efficiency.However,as a new two-way load application technology,its connection strength has attracted much attention from designers.The purpose of this paper is to explore the influencing factors of connection strength based on the limited experimental data.
