| Abstract: |
| To propose the experimental conditions of the shunting impact on the container and obtain the safety boundary under shunting accident. Firstly, two conditions of impact experiments, which were 1 vehicle to 1 vehicle and 1 vehicle to 3 vehicle, were carried out to investigate the longitudinal characteristics of the railway shunting. Then, the vehicle shunting impact model of was built to study the influences of different impact velocities and impact conditions. In the condition of 1 vehicle to 1 vehicle at the impact velocity of 8 km/h, the coupler force was less than 1200 kN. The package inside was fastened tightly after the impact. When the impact velocity equaled to 15 km/h in the condition of 1 vehicle to 3 vehicle, the coupler at the collision interface was compressed to the maximum. After the impact experiment, the coupler of the vehicle was broken. Deformations were appeared at the corner of the container and the back board of the inner package. According to the simulation results, the maximum impact velocity was about 10 km/h, at which the draft gear MT-2 and vehicle structure could keep safe. In the condition of 1 vehicle to 3 vehicle, the coupler force at the front interface of the vehicle with container was about 2132 kN, which was close to the maximum capacity of the draft gear MT-2. In summary, as for the impact experiment on the container under shunting accident, it is much more appropriate to conduct in the condition of 1 vehicle to 1 vehicle. The coupler remains the weak point in the whole vehicle transportation, while the impact velocity boundary is about 10 km/h. |
