Passenger Car Roof Crush Strength Requirements

Roof crush is the failure and displacement of an automobile roof into the passenger compartment during a rollover accident.. Every year approximately 10,000 Americans are killed in rollover accidents, accounting for about 30% of all light vehicle occupant fatalities. The number of occupant injuries is significantly higher. The relationship between injury levels and intrusion or roof crush …


the assessment of bus superstructure and roof. This thesis discusses the development of a finite element (FE) model of a bus, and the analysis of its roof crush and rollover in LS-DYNA. The FE model was validated for the roof crush test carried according to the standard bus procurement guidelines (SBPG). ADAMS-View
