Collision Simulation of Minibus at High Speed

Collision properties of minibus when traveling at high speed are studied. Based on the display dynamics and basic theoretical of contact collision analysis, the front crash finite element model of minibus is built by Hypermesh. The model is simulated under the 50 km/h by ANSYS/Ls-Dyna solver. Finally, the deformation of the front rail, B pillar acceleration curve and the steering column intrusion are got. It is important to improve safety design for minibus.

《非战公约》与田中义一时期的日本外交(1927—1929)

1928年,随着国民政府继续北伐,列强在对华利益的看法上出现显著分歧,日本田中内阁坚决争夺所谓“在华权益”,悍然再次出兵山东,导致自身外交陷入困境,只得重拾前几任内阁的“协调外交”手段。恰逢此时美法两国提出《非战公约》并邀请日本参加这一和平条约,陷于出兵山东泥潭的日本派出签约特使内田康哉前往欧美各国游说,企图将欧美列强拉回一致对华的轨道上,然而《非战公约》引发的“违宪”问题反而拖垮了田中内阁,日本实质上也不可能接受公约对其侵略行为的约束,最终撕毁公约发动战争。直至战败,《非战公约》的精神才真正被写进了日本宪法第九条。
