Fine applicability : it uses imported alloy of hardness as enclosure, ensures the product ' s resistance to shock and impact. with fine water - proof and temperature - proof property, it can be used in underwater 200m and hostile weather
適用性強:進口高硬度合金外殼能承受強力碰撞和沖擊;防水、耐高溫、高濕性能好，可各種惡劣氣候條件下正常工作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。
