In this paper the potential of kinetic energy absorption by means absorbing and storing mechanisms was discussed. The use absorbers is intended to reduce maximum working forces when stopping body.

Collisions between rail transit vehicles are unavoidable. In order to alleviate the disaster caused by collision, energy-absorbing and shock-absorbing materials generally installed at front end of vehicle. this paper, a variable buffer-force planing device for was prepared. The buffer force changed length (Dx), angle (A) thickness (W). First, we manufactured one type material, data were obtaine...
