辅助框架内部环形结构对车体侧面的增强作用

Carbody-Side Strengthening Effects of an Inner Sub-Frame Ring Structure

为确保铁道车辆的生存空间,可将辅助框架连接成车内环形结构附在车体内侧,以提高车体的强度。通过静强度试验和有限元分析,认为该方法可行。

In order to secure the survival space of rolling stock,an inner ring structure can be formed by uniting sub-frames attached to the inside of the carbody,so as to improve the strength of the carbody.The static strength test and finite element analysis prove that the method is feasible.
