Abstract

The invention discloses a coupler force testing calibration tooling. The coupler force testing calibration tooling comprises a platform, a force application component used for providing pulling forceand pressing force and a counter-force component opposite to the force application component are fixed to the platform, the force application component acts on a force sensor, and a coupler transitionsleeve to be calibrated is connected between the force sensor and the counter-force component, so that the acting force of the force application component is applied to the coupler transition sleevethrough the force sensor. The invention further discloses a coupler force testing experimental method, the coupler force testing experimental method comprises the steps that the coupler transition sleeve is installed on the coupler force testing calibration tooling, and a foil gauge is arranged on the surface of the coupler transition sleeve; calibration and verification are carried out, specifically, the force application component separately provides the pulling force and the pressing force, and a output result of the force sensor and a output result of the foil gauge are separately compared; and on-line testing is carried out after the verification is qualified. The coupler force testing calibration tooling provides a reliability basis for coupler force testing, the coupler force testing experimental method can realize on-line testing, understand the all terrain coupler force condition, and provide the basis for coupler optimization design, life evaluation and the like.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, more specifically, to a coupler force test method, and also to a coupler force test calibration tool. Background technique [0002] With the rapid development of domestic rail transit, the number of subway and EMU vehicles is increasing. The coupler is an important part of rail transit vehicles. It refers to the hooks at both ends of the wagon or locomotive, which have the functions of connection, traction and buffering. It is used to realize the connection between locomotives and vehicles or between vehicles and vehicles, to transmit traction and impact force, and to keep a certain distance between vehicles. [0003] As a force-transmitting component between vehicles, the reliability of the coupler is related to the safety of vehicle operation. Different lines, loads, and vehicle speeds have different effects on the coupler. It is particularly important to evaluate the performan...
