Abstract

The invention discloses a rotating arm type axle box force measuring device and a method thereof. According to distribution positions of loads exerted on rotating arm type axle boxes, the normative testing method is specified for vertical loads exerted on shock absorber bases and spring bases and vertical, transverse and longitudinal loads exerted on elastic nodes, so that actual and reliable testing parameters are provided for scientific judgment and measurement of the magnitude and directions of loads exerted on rotating arm type axle boxes. The rotating arm type axle box force measuring method comprises the steps of adopting the force measuring device comprising a loading cross beam and a simulation structure to install four rotating arm type axle boxes on the simulation structure according to actual usage positions; connecting a pair of vertical actuating cylinders between the simulation structure and the loading cross beam in the vertical direction, and connecting a transverse actuating cylinder and a longitudinal actuating cylinder respectively on horizontal side portions of the simulation structure; and connecting a first sensor between a vertical shock absorber and the simulation structure, connecting a second sensor between an axle box spring and the simulation structure, and connecting a third sensor between a node base and the simulation structure.

Description

technical field [0001] The invention relates to a device and a method for measuring multidirectional loads of a pivoting arm type axle box applied to a rail vehicle bogie, and belongs to the technical field of rail transportation. Background technique [0002] With the rapid popularization of domestic urban rail transit and the substantial increase in vehicle speed, higher design and use requirements are put forward for the bogie frame that carries the vehicle body and transmits traction. [0003] At present, the primary suspension system of the bogie used in domestic rail transit generally adopts the axle box positioning method, that is, the axle box pivot arm positioning structure, which is usually defined as the pivot arm axle box. [0004] For example, the prior patent application that discloses the following content, the application number is 201020542266.6, and the name is a series of elastic positioning devices for rail vehicles, which are arranged between the bogie f...
