Application Development of High-speed EMUs Resistance Force Reduction and Weight Lightening

从减小列车运行阻力的目的出发,研究高速动车组气动设计以及轻量化设计的关键技术,通过对影响列车运行阻力的主要因素进行系统分析及优化,提出了高速动车组降噪减重的控制策略及具体措施。线路试验表明,相关措施有效降低了高速动车组的运行阻力,实现了速度提升、节能环保的目标,同时也提升了列车的动力学性能及综合舒适度。

For decreasing the train operation resistance force, key technologies of high-speed EMUs aero-dynamical design and lightweight design were studied. By the systematic analysis and optimization of the major factors to influence train operation resistance force, control scheme and practical measures were proposed for high-speed EMUs noise reduction and weight lightening. Line test showed that the provided measures reduced high-speed EMUs operation resistance force effectively, realized speed lifting, energy conservation and environmental protection, and improved train dynamics performance and synthetical comfort too.
