Abstract
본 연구는 KHP(Korean Helicopter Program) main & nose wheel 국산화 개발을 위한 구조해석으로서 상용프로그램인 ANSYS를 사용하여 wheel의 구조적 안정성을 평가하였다. Wheel과 tire의 interface를 고려한 연구로서, Tire의 공기압과 정하중, 반경하중 그리고 복합하중을 main & nose wheel에 적용하여 응력해석을 수행하였다. 해석결과는 소성변형이 발생하는 항복강도를 고려하여, maximum stress와 항복강도를 비교분석 후 구조적 안정성을 더 높일 수 있는 방안을 제시하였다.This study performed the structure analysis for development and localization of main and nose wheel in Korean Helicopter Program(KHP). Structural stability of wheel is evaluated using ANSYS. Considering wheel and tire interface, Stress analysis was conducted by applying pneumatic of tire, static load, radial load and combined load on main and nose wheel. Considering yield strength at which plastic deformation occurs, simulation results suggest the method which increases structure stability after comparing maximum stress and yield strength.
