Abstract

The invention is suitable for the technical field of rail transit vehicles, and provides a method for reducing vibration of an end wall and a high-damping end wall and device.The method comprises the steps: according to the end wall structure, obtaining structural modal parameters of the end wall structure through calculation; calculating a sensitivity maximum value of the structural mode according to the structural mode parameters; after the particle damper is arranged at the end wall position corresponding to the sensitivity maximum value, calculating the damping coefficient of the particle damper according to the sensitivity maximum value; based on the damping coefficient, analyzing the end wall structure provided with the particle damper to obtain a vibration reduction result, so that vibration of a large structural part can be reduced, the comfort degree is improved, fatigue damage caused by large structural vibration is reduced, and the influence on the existing end wall structure is small, the particle damper only needs to be installed at the position corresponding to the calculated maximum value of the structural modal sensitivity, and installation is convenient.

Description

technical field [0001] The invention belongs to the technical field of rail transit vehicles, and in particular relates to a method for reducing vibration of an end wall, a high damping end wall and a device. Background technique [0002] The global high-speed railway has entered an era of rapid development. High-speed and stable operation is an inevitable trend in the development of rail transit vehicles. The lightweight technology of the vehicle body is to reduce energy consumption during operation, reduce the interaction force between wheels and rails, and achieve high-speed stability. important means of operation. However, excessive pursuit of light weight and speed will often lead to insufficient rigidity of the car body and a decrease in the mode of the car body. During the high-speed operation of the vehicle, the elastic vibration of the vehicle body is intensified, resulting in obvious local vibration of the vehicle body. [0003] The end wall is located at the fle...
