Rail vehicle design for crashworthiness (2nd report, carbody crash test and crash behavior by numerical calculation)

摘要

Numerical simulations of a rail car body crashing against a rigid wall were carried out, and deformation of the car body caused by collision was predicted. By comparison with a test of a full scale model, it was proved that the crash energy was absorbed only by the deformation of car body end structure and that any part of compartment for the driver and passengers was not damaged.
