为了延长检修周期,C_(62A)(N)车体钢结构的主要零部件(含易腐蚀零部件)的材质均采用耐候钢。 本文介绍了C_(62A)(N)型敞车的主要用途、主要技术参数、车体结构概况、钢结构设计及防腐措施。C_(62A)(N)型敞车是载重60t的全钢敞车,其主要结构与C_(62A)型敞车基本相同,仅对车体钢结构主要零部件按等寿命原则重新选定断面尺寸及材质,并按耐候性的要求对车体结构作了相应改进,对结构零部件进行了简统化。
In order to prolong the overhaul period, the main components of C_ (62A) (N) body steel structure (including corrosion-prone parts) are made of weather-resistant steel. This article introduces the main purpose, main technical parameters, outline of body structure, steel structure design and anticorrosion measures of C_ (62A) (N) gondola. The main structure of C_ (62A) (N) gondola is 60t all-steel gondola. The main structure of C_ (62A) (N) is basically the same as that of C_ (62A) gondola. Only the main components of steel structure of vehicle body are re-selected according to the principle of equal life , And according to the requirements of weatherability of the car body made a corresponding improvement, the structural components were simplified.
