本文阐述了客车钢结构从选材和结构设计两个方面提高客车防腐能力的途径。在选材方面,国外趋向用铝合金逐步取代含铜钢和不锈钢;我国则逐步用低合金含铜耐候钢代替普通碳素钢。在结构上,针对下侧梁、侧墙板下部及侧柱的连接节点;上侧梁、车顶过梁及雨檐的连接节点;侧柱、窗台、车窗结合处;侧墙板压筋、大腰带及脚蹬门门框等易腐部位的结构演变情况进行了分析比较,并提出改进建议。
This article elaborates the ways of improving the anti-corrosion ability of passenger cars from the aspects of material selection and structural design. In material selection, foreign countries tend to gradually replace the use of aluminum-containing copper and stainless steel; our country is gradually replaced with low-alloy copper-bearing steel instead of ordinary carbon steel. Structurally, the connection node of the lower side beam, the lower part of the side wall plate and the side column, the connection node of the upper side beam, the roof lintel and the rain eaves, the joint of the side column, the bay window and the window, the side wall plate press bar, Belt and pedal door frames and other perishable parts of the evolution of the structure were analyzed and compared, and put forward suggestions for improvement.
