Parameter determining test bed for gantry framework type rail vehicle bogie

Abstract

The invention relates to a parameter determining test bed for a gantry framework type rail vehicle bogie. The test bed mainly consists of a counter-force type gantry mechanical framework, a six-degree-of-freedom loading mechanism assembly, a bogie transfer bridge device and a bogie positioning and clamping mechanism assembly, wherein the counter-force type gantry mechanical framework provides counter-force support to a test bed loading mechanism and a positioning and clamping mechanism; the six-degree-of-freedom loading mechanism assembly is used for the vertical, lateral and longitudinal loading of the tested bogie; the bogie transfer bridge device is used for smoothly and flexibly transferring the tested bogie to a test bed loading platform; and the bogie positioning and clamping mechanism assembly is used for the vertical, longitudinal and lateral positioning and fixing of a second tested bogie frame. According to the test bed, the tests of parameters, such as the vertical, longitudinal and lateral rigidity of the first bogie and the second bogie, and the bogie torsion rigidity, can be realized, the rigidity coefficient and the flexibility coefficient of each part of the bogie can be automatically calculated by software, and the automation and the efficiency when the bogie parameter is measured are improved.

Description

technical field [0001] The invention relates to detection equipment in the field of rail vehicles, in particular to a gantry frame type rail vehicle bogie parameter measurement test bench. Background technique [0002] The bogie is a key component of a rail vehicle, especially in the high-speed EMU technology, the performance parameters of the bogie itself and its parts directly affect the running quality of the vehicle, and directly determine the dynamic performance, operating safety and Driving stability. In recent years, the development of high-speed passenger cars and heavy-duty freight cars has put forward higher requirements for the dynamic performance of railway vehicles, especially the dynamic performance of bogies. [0003] The development of rail vehicle bogie parameter test bench is related to the development and production of rail vehicle bogie products as well as the structural and theoretical research on the bogie. Therefore, many research institutions and veh...
