An Evaluation of Crashworthiness for the Full Rake KHST Using 1-D Dynamic Model
초록
One of the best methods to evaluate crashworthiness of a full rake trainset is to analyse 1-dimensional dynamic model using dampers, nonlinear springs and bars, and masses. In this study, the crashworthiness of KHST has been evaluated by analysing a nonlinear dynamic model made up of springs/bars-dampers-masses. The numerical results show that the KHST can absorb more kinetic energy at lower impact forces and lower accelerations in case of heavy collisions, if compared with KTX. Also, the KHST can be protected from any damage in its car-body and electric components except the energy absorbing tube in case of light collisions, like train-to-train accidents at speed under 8 kph. On the other hand, the KTX may be more damaged in the light collisions because there is no energy absorbing tube.
