Car-to-Car Frontal Impact Modeling using Spring-Mass Model

Spring-Mass 모델을 이용한 차대차 정면충돌 모델링

The objective of this study was to construct the spring-mass models for the car-to-car frontal impact crash. The SISAME software was utilized to extract the spring-mass models using the data from US-NCAP frontal crash tests. The spring-mass models of a compact car and a midsize car could effectively approximate the crash characteristics for the full frontal barrier impact and the car-to-car frontal impact scenarios. Compared to the barrier crash tests, the dummy injuries of midsize car decreased, while the dummy injuries of compact car increased, under the frontal car-to-car crash circumstances.
