A Development of the Numerical Huge Obstacle Model for the Korean Rollingstock Safety Regulations
국내 철도차량안전법 요구 압괴 성능의 대형장애물 수치모델 개발
Abstract
This study aims to develope a numerical model of the huge obstacle defined in the Korean Rollingstock Safety Regulations. The shape and mechanical properties to be satisfied in the numerical model were based on the Regulations. Through a troublesome trial and error simulations, we developed the numerical model of the huge obstacle to satisfy physical properties of the specified guideline in the regulations. By applying the developed numerical obstacle, we carried out a crash simulation to evaluate vehicle crashworthiness.
