摘要

变轨距除了轨距发生改变以外，还可能伴随有钢轨轮廓、轨底坡的变化，变轨距高速动车组对这些变化都要有较好的适应性，不仅稳定性要满足高速运行要求，而且其他动力学性能也要达到优良水平。变轨距转向架由于增设了变轨机构，增加了簧下质量，文章计算分析了变轨距动车组对这些变化的适应性。计算结果表明，变轨距动车组对轨距、钢轨轮廓、轨底坡及簧下质量变化的适应性较好，满足设计要求。

Abstract

Gauge changeable high-speed EMUs need to adapt to gauge changes, rail profile and gradient changes, to meet the high-speed operation stability and other dynamic performance requirements. Due to additions of gauge-changing mechanism and increasing the unsprung weight, the adaptability of the gauge changeable EMUs to these changes was calculated and analyzed. The calculation results showed that the gauge changeable EMUs have good adaptability to gauge, rail profile, rail bottom slope and unsprung weight, which met the design requirement.
