并以端墙式隧道门为例，对隧道洞门可靠度进行了计算。

In addition , the reliability index of end wall portal structure was calculated as an example .

铁路货车生产品种众多，货车端墙结构形式各异。

Among the products of many varieties of the freight wagons , wagon end wall structure is different .

货车端墙属于薄板结构，在焊接生产过程容易发生失稳，产生波浪变形。

Truck end wall belongs to thin plate structure , so it easily occurs instability and produces waves deformation in welding process .

为铁路货车端墙配套的焊接机器人生产线，除了两套焊接机器人系统之外，设计制造了外围机械系统与电控系统。

Except two welding robot system , we designed and produced periphery mechanism and electric control system of the welding robot product line used for manufacturing train truck end wall .

基于刚度等效原理确定散粒煤的性能参数，C80B车体的边界非线性有限元分析表明：车体端墙静压力分布沿端墙高度呈近似三角形分布。

Based on the stiffness equivalence principle to determine the parameters of granular coal , the boundary finite element analysis showed : the side wall static pressure distribution along the side wall height was similar triangle .

当约束方案相同时，不同焊接顺序下，端墙的最大变形量位置分布基本相同。

And deformation of the end wall is minimal at this time . ( 4 ) Under the same constraints and the different welding sequence , the maximum deformation of the end wall position distribution is basically the same .

然而，随着车辆载重的增大和运行速度的加快，重载敞车车体出现了端墙外胀严重、端墙支撑根部出现裂纹等问题，对重载货运的安全已经构成了相当大的威胁。

However , with the vehicle load and the speed increasing , heavy-duty gondola car body appeared serious issues , such as side wall bulge and the root of the crack which has posed a considerable threat on heavy-duty transportation security .

我国传统铁路隧道洞门根据地形特点分为基本型、变化型、和特殊型三大类十六种形式，但始终脱离不了端墙、柱式的形式。

In China , traditional portal of railway tunnel can be sorted as three types-origin , modified and special types , inclusive of 16 kinds on basis of the characteristic of terrain , basically they are of end wall and post type .

以往端墙组焊采用刚性工艺装备，更换一个品种需要更换或调整一套组焊装备，存在准备周期过长、装备利用率低、生产成本高等问题。

The past , use a rigid welding equipment , replacement of a species need to be replaced or adjusted in a set of welding equipment , there is preparation cycle is too long , and equipment utilization is low , the problem of higher production costs .

试件的破坏形态主要是钉节点的破坏和端部墙骨柱的上拔。

Failure of the shear walls are mainly in the mode of nail connection failure and uplift of end studs .
