我国高铁客运的发展处于世界前列水平,其中轻量化和高速化成为以高铁为主的我国快速列车在设计和制造时遵循的主要原则和标准。其中高速化主要通过提高列车的运行速度,减少单趟客运所需的时间,从而增加客运频率,提高经济效益,但随之产生的是高频率的激扰现象,轻量化则是降低车辆结构的本身刚度达到整体质量的减轻,但从而产生的是自身结构振动频率的降低,高速化和轻量化在高频的激扰和低频的振动间产生共鸣,容易恶化高铁列车的动力学性能,因此本文将从车体振动程度和车体结构的关系着手,研究高铁列车如何实现高速化和轻量化之间的最佳匹配,探讨高铁列车车体结构和振动对动力学性能的影响。
The development of high-speed rail passenger transport in our country is at the forefront of the world. Among them, the light-weight and high-speed railways have become the major principles and standards followed by China’s rapid rail rapid trains designed and manufactured with high-speed rail. Among them, the speeding up mainly increases the running speed of the train and reduces the time required for single-trip passenger transportation, thereby increasing the frequency of passenger traffic and increasing the economic benefits, but the resulting high-frequency disturbing phenomenon and the light-weighting reduce the vehicle structure The rigidity of the train itself is reduced to the overall quality, but the vibration frequency of the train itself is reduced. High speed and light weight resonate between the high frequency disturbance and the low frequency vibration and easily deteriorate the dynamic performance of the high speed train. Therefore, Starting from the relation between the vibration degree and the structure of the car body, this paper studies how the high-speed train can achieve the best match between high speed and light weight, and discusses the influence of the structure and vibration of the high-speed train on the dynamic performance.
