摘要
为助推成渝地区双城经济圈建设,成渝中线将以最终开行400km/h高速轮轨动车组为目标,实现更高速度高速铁路技术的示范和引领。400km/h高速动车组技术指标的确定,对成渝中线工程以及整个国家更高速度铁路网都至关重要。本文基于既有400km/h高速动车组技术现状,开展了更高速度等级车辆最高设计速度、剩余加速度、轴重、功率、制动距离、减阻能力等主要技术指标的分析研究,提出了适用于成渝中线400km/h速度开行的“优化400”高速动车组概念设计方案,以及主要参数目标和相应的优化措施。
In order to boost the construction of Chengdu-Chongqing economic circle,the high-speed wheel-rail EMU will eventually run at a speed of 400 km/h on the Chengdu-Chongqing middle line as the goal to realize the demonstration and guidance of high-speed railway technology with higher speed.The determination of technical indexes of 400 km/h high-speed EMU is very important not only for Chengdu-Chongqing middle line but also for the higher speed railway network of the whole country.Based on the current situation of the existing 400 km/h high-speed EMU technology,the maximum design speed,residual acceleration,axle weight,power,braking distance,drag reduction ability and other main technical indexes of higher speed grade vehicles are analyzed and studied.A conceptual design scheme called as Optimization 400 is put forward for running at a speed of 400 km/h on the Chengdu-Chongqing middle line.And the main parameter target and corresponding optimization measures of the EMU are proposed.
