车体钢结构在检修过程中,损坏形式主要有变形、裂损、腐蚀等三种。其中以腐蚀最为严重,腐蚀绝大部分是由里向外,尤以搭接结构处更为严重。当然腐蚀的原因有设计上的,有工艺上的,也有使用不当引起的。下面就设计上的不合理,提出几点看法,以便今后能够改进。 Body steel structure in the overhaul process, the main form of damage are deformed, cracked, corrosion and other three. Among them, the most serious corrosion is caused by corrosion, most of which is from the inside to the outside, especially at the overlapping structure. Of course, the causes of corrosion are design, process, but also caused by improper use. Below on the design of the unreasonable, made a few comments, so that in the future can be improved.
