民用飞机起落架缓冲器选型与对比分析研究
Research on Types and Comparisons of Landing Gears Shock Absorber for Civil Airplane
摘要
Abstract
The nose landing gear and main landing gear are chosen as subjects to investigate in this paper.At first,by using Delphi and SQL Server,the parameter design program of the shock absorber is developed.The parameters of single-acting shock absorber,single-acting shock absorber with a metering pin for the nose landing gear and single-acting shock absorber,double-acting shock absorber for the main landing gear are calculated.Then the virtual prototypes of the nose landing gear and main landing gear for dynamic analysis of landing gear impact are established on ADAMS/Aircraft.There is a good correspondence between the simulation results and required results.Finally,the comparison analysis of different shock absorber types is given.As a result,the efficiency is higher using the single-acting shock absorber with a metering pin.The load factor is lower using the double-acting shock absorber in the condition of the high sink speed.关键词
