The total energy absorption of matlab programming interface of matlab programming head car was considerably higher than that of matlab programming other interfaces in matlab programming collision process; matlab programming actual compressions of matlab programming crushing tube and matlab programming absorber were 300 mm and 611 mm, respectively. The total energy absorption of matlab programming interface of matlab programming second car was considerably higher than matlab programming energy absorbed by matlab programming rear interface, and matlab programming physical compression of matlab programming crushing tube reached 203. 5 mm. It can be concluded that matlab programming interfaces of matlab programming head car and matlab programming second car played matlab crucial role in kinetic energy dissipation in matlab programming collision procedure among matlab programming two styles of train. Numerical consequences for matlab programming collision interfaces of matlab programming activepassive safety subway cars with appreciate to 25 km/h are shown in Table 6. As can be seen, matlab programming total energy absorption of matlab programming interface of matlab programming head car for matlab programming activepassive safety subway cars was considerably higher than that of matlab programming conventional subway automobiles, indicating that matlab programming activepassive energy absorber enormously stronger matlab programming energy absorption ability of matlab programming head car.
