Method and system for evaluating vibration comfort of transient violent vibration of train body

Abstract

The invention discloses a method and system for evaluating the vibration comfort of transient violent vibration of a train body. The method comprises the steps that a train body roll angle and the transverse displacement of a gravity center position in the train operation process are measured in a strong wind environment; frequency weighted filtering is carried out on the train body roll angle thetransverse displacement of a gravity center position; the train body roll angle obtained after weighted filtering and the transverse displacement of the gravity center position after weighted filtering are cut off according to a period, and the absolute value and peak-to-peak value of the average value of the train body roll angle the transverse displacement of the gravity center position are solved according to intervals; according to the absolute value and peak-to-peak value of the average value of the train body roll angle the transverse displacement of the gravity center position, evaluation indexes of the vibration comfort of a train are obtained through calculation. According to the method, the vibration comfort condition of the transient violent vibration of the train body in the train operation process can be more accurately reflected, and the actual feeling of a driver and passengers of the train can be reflected more accurately.

Description

technical field [0001] The invention relates to the field of high-speed train operation evaluation, in particular to a method and system for evaluating vibration comfort caused by transient severe vibration of a train body when a train passes through a complex terrain section in a strong wind environment. Background technique [0002] With the continuous development of high-speed rail technology, more and more attention has been paid to the comfort of train riding. Train ride comfort is related to many factors, such as vibration, noise, temperature, occupants, and vehicle design, etc. It is quite difficult to evaluate ride comfort by considering all the above factors at the same time. Therefore, in the field of railways, ride comfort generally refers to the passenger's acceptance of the vibration of the car body system during the operation of the train. [0003] At present, there are two main categories of comfort evaluation, one is the overall physiological feeling of the ...
