Detection technology of friction block of brake pads in non-stationary train
The wear of the brake pads of non-stationary running trains is relatively large,and the direction of their travel devia-tion always remains consistent with the direction of friction block wear.This leads to the inability to obtain differentiated characteristics of the friction block's eccentric wear state,and the inability to determine the actual direction of travel deviation of non-stationary run-ning trains.Research is being conducted on the detection technology for the eccentric wear status of brake pads and friction blocks in non-stationary running trains.Determine the distribution of debris on the surface of the brake pad friction block,model and analyze the flow behavior of debris,and complete the description and conversion of eccentric wear data under the Gram angle field.Extract the eccentric wear characteristics from the data of eccentric wear behavior,decompose the specific conditions of eccentric wear character-istics,collect the entire driving cycle,form a set of eccentric wear state characteristics,calculate the deflection amount of debris be-havior under contact/separation,and then obtain the strength of contact force and separation force,achieve the optimal solution of ec-centric wear characteristics,and complete the design of the detection method for the eccentric wear state of the brake pad friction block of non-stationary running trains.The experimental results show that the detection results of the obtained eccentric wear state are the same as the actual degree of eccentric wear of the friction block,for the train control host;It will not cause erroneous definitions due to inaccurate detection of eccentric wear status,nor will it affect the direction of non-stationary train operation.
