根据1991年中苏首届航空结构强度学术交流会上原苏方的有关技术报告,简单地综述了原苏联飞机结构耐久性和损伤容限(包括热应力)分析方法和试验方法。这些方法建立在正确的理论分析及大量的试验和使用经验基础上,合理地确定新机的寿命期限和逐步地延长在役飞机的寿命期限,确保飞机结构的完整性。
According to the technical report of Uehara Su from the First China-Soviet Symposium on Aviation Structural Strength in 1991, the methods and test methods of the durability and damage tolerance (including thermal stress) of the former Soviet Union aircraft were briefly reviewed. These methods are based on the correct theoretical analysis and extensive experience in experimentation and use. They should rationally determine the life span of the new aircraft and gradually extend the life of the aircraft in service to ensure the structural integrity of the aircraft.
