Train provided with energy absorbing structure between vehicles

A train having an energy absorbing structure between cars comprising:

• a plurality of cars coupled to one another;
• and
• energy absorbing structures each provided between cars, wherein
• an average compressive load which is obtained by dividing an energy absorption capacity of each energy absorbing structure by a maximum compression amount of the energy absorbing structure is set equal at interfaces between cars in an entire train, and
• at each interface between cars, an average compressive load of latter-half compression which is obtained by dividing an amount of an energy absorbed by the energy absorbing structure while compression amount of the energy absorbing structure varies from a half compression amount that is half as large as a maximum compression amount to the maximum compression amount by the half compression amount, is set to a value of not less than a maximum compressive load generated while the compression amount of the energy absorbing structure varies from zero to the half compression amount of the maximum compression amount and a value of not more than an average compressive load of the energy absorbing structure at a front portion of a front car of the train.

• a plurality of cars coupled to one another;
• and
• energy absorbing structures each provided between cars, wherein
• an average compressive load which is obtained by dividing an energy absorption capacity of each energy absorbing structure by a maximum compression amount of the energy absorbing structure is set smaller at an interface between cars at a center portion of the train than at an interface between cars closer to an end portion of the train, and
• the energy absorbing structure at least one interface is configured such that an average compressive load of latter-half compression which is obtained by dividing an amount of an energy absorbed by the energy absorbing structure while the compression amount of the energy absorbing structure varies from a half compression amount that is half as large as a maximum compression amount to the maximum compression amount by the half compression amount, is set to a value of not less than a maximum compressive load generated while the compression amount of the energy absorbing structure varies from zero to the half compression amount of the maximum compression amount and a value of not more than an average compressive load of the energy absorbing structure at a front portion of the train as a value obtained by dividing an energy absorption capacity of the energy absorbing structure at the end portion of the train by the compression amount of the energy absorbing structure at the end portion of the train.
