wall collision

The hollowing model created by the algorithm was constant wall thickness and no collision.

其优点是生成的镂空模型的壁厚比较均匀,无干涉现象.

The collision simulation is made on a certain type of locomotive car-bodies mounted with the energy absorption ( equipment) consisted of the thin-wall structure. The result shows that the structure has fair good energy absorption performance.

对安装了由薄壁结构组成的吸能装置的某机车车体进行了碰撞仿真，结果表明该结构具有较好的吸能性能。

Chinese people will never allow any foreign force to bully17, oppress, or subjugate15 us. Anyone who would attempt to do so will find themselves on a collision course with a great wall of steel forged by over 1.4 billion Chinese people.

中国人民也绝不允许任何外来势力欺负、压迫、奴役我们，谁妄想这样干，必将在14亿多中国人民用血肉筑成的钢铁长城面前碰得头破血流！

Research on the Thin-Wall Structure of the Energy Absorption Equipment on the Collision Resistant Car-body

耐碰撞车体吸能装置的薄壁结构研究

The explicit finite element is used to simulate the effect of cross section, wall thickness and preliminary deform, et al. on the collision resistant performance. The collision law of the thin-wall structure is found out.

利用显式有限元模拟仿真了薄壁结构的横截面、壁厚和预变形等对其碰撞性能的影响，找出了薄壁结构的碰撞规律。
