Abstract

The invention discloses a method for analyzing static strength characteristics of a brake clamp. The static strength and the modal of a brake clamp are subjected to simulation calculation analysis through finite element software, the maximum stress of each component of the brake clamp is quickly obtained through a simpler calculation mode, and the calculation precision of the static strength of the brake clamp can be improved by adopting the calculation mode, so that the brake efficiency of a train is improved.

Description

technical field [0001] The invention belongs to the technical field of maglev trains, in particular to a method for analyzing the static strength characteristics of a brake caliper. Background technique [0002] The brake caliper is the executive part of the brake system of the maglev train. The electronic brake control unit (EBCU) controls the hydraulic brake control unit (HBCU) to provide pressure oil for the brake caliper according to the train command. The piston on the brake caliper Under the action of pressure oil, the rod pushes the brake disc to clamp the F rail to brake the train. [0003] At present, the static strength calculation of the brake caliper generally adopts a pressure sensor on the hydraulic part of the brake caliper, and the maximum emergency braking force of the brake caliper to the F rail under the maximum working condition is measured by the pressure sensor, and then through Complicated calculation calculates the static strength of the brake calipe...
