Vehicle brake shoe braking force calculation method, device, equipment, medium and system

Abstract

The embodiment of the invention relates to the field of railway vehicle braking force measurement, and discloses a vehicle brake shoe braking force calculation method, device, equipment, medium and system, and the method comprises the steps: obtaining the wavelength of light collected by each optical fiber sensor in the braking process of a target vehicle; the force borne by each optical fiber sensor is calculated according to the wavelength and a pre-calibrated force coefficient, the force borne by the optical fiber sensors on the two bevel edges of the same brake beam represents the first braking force borne by the brake shoes correspondingly connected with the two bevel edges, and the force borne by the optical fiber sensor on the middle pull rod represents the second braking force borne by the middle pull rod; the force coefficient is a conversion coefficient between the wavelength and the braking force; for each bogie, the vertical braking force borne by each brake shoe is calculated by utilizing the force borne by the two bevel edges of the same brake beam and the force borne by the optical fiber sensors on the middle pull rod. According to the method disclosed by the invention, the problem that the vertical braking force of each brake shoe in the braking structure is independently calculated in the vehicle braking process is solved, and the friction force is prevented from interfering with the braking control effect.
