RecurDyn을 이용한 항공기 착륙 시뮬레이션 (Landing Simulation of Aircraft using RecurDyn)
Abstract :
When aircraft accidents happen, it causes serious damage to aircraft and can lead to personal injury. Most of aircraft accidents occur during landing especially, thus many researches are carried out in aircraft landing simulation using finite element method. However it is very time consuming and require many effort to generate models and analysis because finite element model has a number of degree of freedom which is the independent parameters that define its configuration. Using RecurDyn, a multi-body dynamic analysis program, shock absorber is designed by lumped model and Fiala tire is used for tire model. Then both models are verified with theoretical result. Furthermore, spin-up and spring-back phenomena are confirmed when longitudinal velocity is included.
