飞机牵引车刹车工况下起落架受载分析
Stress Analysis of Landing Gear In Tractor's Breaking Operating Mode
摘要
Abstract
In order to ensure the safety of aircraft ground traction,this paper analyzes the effect of impact load caused by sudden breaking on the drag strut of nose landing gear.It takes a certain type of aircraft as the reference model and establishes the contact -impact force model of towed system,based on Adams.The processes of starting up,uniform motion and sudden braking during tractor towing aircraft are simulated,to measure the load on the drag strut of nose landing gear,which is caused by traction load.In addition,the buckling analysis of the drag strut is done through the theoretical calculation and the finite element method.The analysis result shows that the drag strut's structural stability can be damaged by the impact load caused by sudden braking.关键词
