底架

The application in Zhenhua Port Machinery Company greatly reducing engine underframe design time, effectively shortening the product development cycle, the system is described successful.

在振华港口机械公司的应用，大大减少机房底架的设计时间，有效地缩短产品开发周期，说明了本系统是成功。

Based on the characteristics of railway vehicles, the crashworthy subway vehicle was designed. The design concept of crashworthy car-body was proposed and the energy-absorbing process of the head car impact was divided into four steps: the first step is the rubber buffer of the buffer equipment of vehicle coupler; the second is the buffer with collapsible tube; the third is the cut bolt of vehicle coupler; the fourth is the special energy-absorbing structures and the anti-climbers on the underframe of head car.

针对地铁车辆自身特点进行耐冲击地铁车辆吸能结构设计，提出了耐冲击地铁车辆设计理念，将该地铁头车在撞击过程中的能量吸收过程设计为4级：第1级为车钩缓冲装置缓冲器，第2级为缓冲装置中的压溃变形管，第3级为车钩剪切螺栓，第4级为位于头车前端底架的吸能结构和防爬器等可变形结构。

Afterwards, the crash process of the thin-walled structure is simulated to find the effect of the cross section, the thickness and the pre-deformation on the crash capacity, and the axial impact deformation of the circinal tube is analyzed in the theoretical way, the axial impact deformation of the square tube and subulate tube are analyzed by simulation.

最后本文建立了原DF_(8B)机车车体正面碰撞刚性墙的仿真模型，在分析碰撞结果后，对原DF_(8B)机车车体的底架和司机室结构进行了改进；并利用薄壁圆管和锥形结构设计了吸能装置，利用凸凹相见的防爬板设计了防爬装置；对安装了吸能装置和做出结构改进的耐碰撞DF_(8B)机车以10m/s和15m/s速度正面撞击刚性墙进行仿真，结果表明碰撞时吸收装置先于车体主结构破坏，吸收碰撞能量，其吸能能力达到了国外有关标准的要求。

This is achieved with a crosspoint switch that has a nonblocking path for each card in either a 4-by-4 or 16-by-16 matrix for a four- or 16-slot chassis, respectively.

这是利用一个交叉点开关实现的，对4插槽或16插槽的底架而言，该开关分别以4×4或16×16的矩阵形式，拥有每块卡的一条无阻塞通道。
