Vibration Response Analysis of Gearbox Housing of High Speed Train Under Wheel and Rail Excitation

摘要：

　　In order to understand the true vibration characteristics of the gearbox housing during operation,the time domain analysis of the different positions of the gearbox housing should be carried out.This paper introduces the modeling and research methods of the vibration characteristics response of the gearbox housing of high-speed trains,and analyzes and verifies the data of each measuring point under the case of driving in a straight line.The main modal parameters of the acceleration response of each position of the gearbox housing are obtained through comparison.The result provides reference value for structural improvement of the gearbox housing of high-speed trains.
