SIMULATION OF URBAN RAIL VEHICLE CRASH AND FACTORS INFLUNCING ANTI-CLIMBING ABILITY OF ITS ANTI-CLIMBER
By use of the finite element software Hypermesh and LS-DYNA,the processes were respectively simulated of urban rail vehicle head car,with and without anti-climbing energy absorption device,impacting the fixed rigid wall face to face at the speed of 12.25 km / h and 18 km / h.Based on the obtained da...

| description | By use of the finite element software Hypermesh and LS-DYNA,the processes were respectively simulated of urban rail vehicle head car,with and without anti-climbing energy absorption device,impacting the fixed rigid wall face to face at the speed of 12.25 km / h and 18 km / h.Based on the obtained data,the crashworthiness of urban rail vehicle head-car body and performance of its energy absorption device were evaluated.Using the response surface methodology,the factors influencing anticlimbing ability of anti-climber were also studied.The results show that,when the crash speed is respectively at 12.25 km / h and18 km / h,the energy absorption device would absorb impact energy before car body structure by plastic deformation,protecting the car body without and with only a little plastic deformation.In addition,when the total height and tooth thickness of anti-climber are fixed,its anti-climbing ability would decrease as the tooth height and angle increases,and the tooth height has more influence than the angle. |
