Research of Vibration Ride Comfort Test Methodology for High-speed Train
摘要
Abstract
vibration almost all With speeding up performance, has of the railway, the great changes, the train body dynamic modals that can＇t be arouse under high speed situation, and arise secondar performance, especially stimulated at low speed y vibration at the same time. Meanwhile, the adornment and layout of the high-speed train are totally changed. The original testing method of train body vibration ride comfort is on the basis of vibration parameters at medium and low speeds, there are many testing contents and testing methods can＇t exemplify or completely illustrate the vibration of the high-speed multiple units. In this paper, the testing method and analysis contents of vibration ride comfort have been researched according to the vibration performance of the high-speed train. According to the test data, the acceleration value distribution characteristics at different positions in a compartment were analyzed. The acceleration value change tendency was analyzed at different speeds. The vibration comfort value changes were analyzed in the open and tunnel lines respectively. The improvement testing scheme was put forward to test.关键词
