three-body collision 中文意思是什麼
three-body collision
解釋
三體碰撞-
In order to reduce the losses suffered from collision between passenger trains, a new design method for the car body structure of motor car and trailer is advanced. car body structures are made up of three parts with diffferen tstiffness, by carefully designed. the parts of the front and the end are the wea kstiffness structure to absorb energy through plastic deformation in the collision. the middle part, where only elastic deformation occurs, is an elastic deformati on structure with strong stiffness. as the passenger train runs normally, car body structure measure up to regulation of intensity and stiffness in the standards
為了減輕客運列車碰撞事故造成的損失，實現被動安全保護，對組成列車的動車、客車車體結構提出了新的設計方法，重新分配車體各部分剛度，設計出具有合適吸能結構的耐沖擊車體，車體結構均按前、中、后三種縱向剛度設置，前後兩部分為可以產生塑性變形的弱剛度吸能結構，中間部分為僅產生彈性變形的強剛度彈變結構。
