- Abstract:
- Energy-absorbing struclure is an important component to ensure that the metro train has a gooderashworthiness. In order to realize the optimization of the energy-absorbing structure , finite element analysissoftware ANSYS/lS-DYNA is used to simulate the crash performance of thin-wall structures of various thick.ness , cross-section. ’The results show that the performance of energy-absorbing component is closely related tocross section and thickness. The same conditions, absorption capability of energy-absorbing component is pro-portional to thickness , however ,interface force increases with the increase of thickness,therefore ,in the designof energy-absorbing component,it is necessary to consider it fully. Take the metro vehicle for example ,one met.ro vehicle equipped with the energy absorption component is put up to simulate the collision procedure ,and thedeformation of the energy-absorbing component and the collision energy-time course are obtained,the resultsshow that this energy-absorbing component has good energy absorption performance.
