- Abstract:
- Energy-absorbing device is the key component to improve the crashworthiness of the rail vehicles.This paper introduces metal cutting technology into the field of passive safety protection of rail vehicles, andproposes the use of chip generation process to absorb the impact energy of the train, and this process is to treatas the energy-absorbing principle of new energy-absorbing device, T’he three-dimensional simulation for the en-ergy-absorbing process in metal-cutting way of metal thin-walled structure is caried out with explicit finite ele.ment, the inflience of tool rake angle on the absorption characteristics of thin-walled structures is analyzed,and energy-absorbing process of metal thin-walled structure in metal-cutting way is compared with the compres.sion. The results show that: the energy-absorbing process in metal-cutting way is a very ideal impact energyabsorption principle of rail vehicles.
