Abstract

To solve the defect of rear protective device of a truck which has no function of barrier and buffer energy-absorbing, a truck-mounted removable type rear protective device is designed. The impact energy is absorbed by mechanical shearing the metal bolt, is mainly used for highway truck is forced to stop, to prevent the rear of the vehicles (especially cars) drill into the bottom of the truck, which lead to great casualty. Utilizing software PRO / E and ANSYS / LS-DYNA carries on modeling and simulation. The results shows that the energy-absorbing device can be decomposed disposable collision energy, gradually reduced the collision force and gradually absorbed the energy, fundamentally avoided the car drill into the bottom of the truck to decrease collision loss and protection. According to the simulation result in full-scale collision and the energy-absorbing characteristics of thin-walled component, that put forward some improvement measures.
