Analysis and application of energy absorption characteristics of expansion tube type absorber
Passive safety protection technology is to reduce the damage caused by collision by improving the anti-impact performance of the system itself.It has important engineering practical value.Many scholars have carried out the research on the collision design of the train in the structure design of the track vehicle.The core is to absorb the kinetic energy of the collision by absorbing energy structure to reduce the force generated during the collision and minimize casualties.The expansion tube type absorber is usually used as a collision safety protection device in the track vehicle.The quasi-static compression test is carried out for the expansion tube type absorber.The energy absorption characteristics and compression characteristics of the expansion tube energy absorber in quasi-static compression test are studied experimentally.The design and research of the energy absorber for rail vehicles are of guiding significance and practical value.
