2019-10-11 · Consider a large truck carrying a heavy load, such as steel beams. A significant hazard for the driver is that the load may slide forward, crushing the cab, if the truck stops suddenly in an accident or even in braking. Assume, for example, that a 10,000 kg load sits on the flat bed of a 25,000 kg truck moving at 14.0 m/s.

heavy truck rollovers often resulted in crushing of the cab roof nearly down to the instrument panel. The deformation was generally not simply straight vertical displacement, but a combination of lateral and/or longitudinal matchboxing of the upper cab structure with vertical displacement of the roof as illustrated in Figure 3. Figure 2.

There is very little difference in results between quasi static and dynamic rollover. An un laden truck is used to simulate the rollover. A side platen is impacted to simulate the phase-1 of the rollover. Energy depending on the mass of the vehicle is imparted in phase-1. Phase I will end once this energy is completely absorbed by the cab.
