高速动车组防脱落底板的结构设计

Structural Design of High-speed EMU Anti-shedding Bottom Cover

针对高速动车组车身轻量化的要求,文章介绍了一种具有防脱落结构的轻型铝合金底板,结合底板的设计要求,进行结构分析,并对底板结构进行强度计算,通过振动冲击试验验证这种防脱落底板的可靠性。

In order to meet the requirement of light weight of high-speed EMU body, this paper introduces a kind of lighttype aluminium alloy bottom cover with anti-shedding structure. According to the design requirements of the bottom plate, analyses the structure, calculates the strength of bottom plate, verify the reliability of the anti-shedding bottom cover by shock and vibration tests.
