Nowadays , mono - line mode is adopted in most domestic motor vehicle safety performance detecting & control system . with the boom of motor vehicle , the efficiency of the existing mono - line is far from requirement , and instead , multi - lines mode turns popular in automobile safety testing supervisory control system 目前,国内的各类机动车检测站大都是单线工作,然而对于机动车数量急剧增加的社会现状来说,现有的单条检测线的效率已经远远不能满足要求,拥有多条检测线并行工作的大型机动车安全性能检测站将是社会需求的必然产物。
Abstract : 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 文摘:为了减轻客运列车碰撞事故造成的损失，实现被动安全保护，对组成列车的动车、客车车体结构提出了新的设计方法，重新分配车体各部分刚度，设计出具有合适吸能结构的耐冲击车体，车体结构均按前、中、后三种纵向刚度设置，前后两部分为可以产生塑性变形的弱刚度吸能结构，中间部分为仅产生弹性变形的强刚度弹变结构。
