摘　　要：险随着世界高速铁路向更高速度发展,噪声已成为高速铁路运营面临的关键问题之一。总结了中国在高速铁路噪声控制领域开展的创新性工作与取得的成效,分析了国外新一代动车组采取的减阻降噪优化设计方案,结合中国CR400动车组更高速度等级时噪声源分布特征,从车体轻量化、转向架包覆、车体表面平顺化及低阻力受电弓等方面提出CR450动车组噪声控制的重点优化方向,并建议同步推进基础设施减振降噪产品的推广应用,从“车-线-传播途径”等方面开展全方位系统性攻关,明确中国更高速度等级高速铁路噪声防治的要求和发展方向。As the high-speed railways in the world develop faster and faster,noise has become one of the key issues in highspeed railway operations.By summarizing the innovative work and achievements in noise control of high-speed railway in China,investigating the conducting research on the low noise optimization designs adopted by the new generation high-speed trains abroad,and combining with the distribution characteristics of noise sources at the higher speed of Chinese CR400 EMUs,key optimization directions for noise control of CR450 EMUs were proposed from the aspects of light weight,bogie wrapping,surface smooth,and low dynamic resistance pantograph.Meanwhile,the promotion and application of infrastructure vibration and noise reduction products is suggested to be carried out simultaneously.Comprehensive and systematic breakthroughs should be made from the perspective of"vehicle-line-propagation paths"so as to clarify the requirements and development trend of noise prevention and control on China's high-speed railway for a higher level of speed.
