Optimization of Lug Design Based on Damage Tolerance Analysis

Abstract:

Article Preview

Lugs are numerous in aircraft and most of them are key structures in aircraft, in which fracture break occurs frequently. It is necessary to improve the fatigue life level of the lugs. In this thesis, the genetic algorithm is used to optimize the crack propagation life of the lugs with or without interference bushes. The curves of optimization results with different safety margin are gained, which can guide the damage tolerance design of the lugs in engineering.
