The Analysis of Relationship between Vehicle Drop & Dummy Injury
Given the importance of vehicle safety, OEMs are focused on ensuring the safety of passengers during car accidents. Injury is related to the passenger’s kinematics and interaction with airbag, seatbelt, and vehicle drop. However, the correlation between vehicle drop (vehicle pitch) and passengers’ injury is the main issue recently being discussed. This paper presents the definition of vehicle drop and analyzes the relationship through a dynamic sled test. This study defines the relationship between individual vehicle systems (body, chassis, tire, etc.) and vehicle drop, and how to control the amount of vehicle drop to minimize the injury of passengers.
