Abstract

The invention relates to detection equipment of a kinetic parameter of a railway car, in particular to an integrated dynamic testboard of a parameter of a bogie of a railway car, which comprises a multi-freedom degree dynamic loading platform (A) and a lift type loading gantry (B), wherein the multi-freedom degree dynamic loading platform (A) mainly comprises a combined type cast steel reference platform (a), a peripheral hydraulic unit (b), a truss longitudinal limit device (c) and a multi-freedom degree sliding table loading device (d); the lift type loading gantry (B) mainly comprises a lift type gantry side beam assembly (e), a lift type gantry cross beam (f), a vertical loading assembly (g) and a lift type gantry sill beam (h). The testboard can carry out dynamic test on the rigidity parameter of a bogie under two states of carload completion and independence by regulating the truss longitudinal limit device (c), the lift type gantry cross beam (f) and the vertical loading assembly (g) without disassembly, and thereby, the goal of integrated multi-function test is achieved.

Description

technical field [0001] The invention relates to a detection device for a dynamic parameter of a railway vehicle, in particular to an integrated dynamic test platform for a bogie parameter of a railway vehicle. Background technique [0002] The dynamic parameters of the railway vehicle bogie mainly include the vertical stiffness, transverse stiffness, longitudinal stiffness, radial stiffness, slewing stiffness and slewing friction moment of the primary and secondary sets, and these parameters directly affect the speed, stability, and Comfort and safety. Therefore, it is very necessary to accurately test and research the main parameters of the railway vehicle bogie. At present, there are not many equipments for testing the dynamic parameters of railway vehicle bogies, and there is no record of equipment that can perform dynamic testing of parameters of the whole vehicle bogie and independent bogies without dismantling. [0003] 1. The technical situation of bogie testing equ...
