Description

For portal frame type parameter of bogie test board framework positioning clamping device
Technical field
The present invention relates to parameter of bogie test checkout equipment, particularly relate to a kind of for portal frame type parameter of bogie test board framework positioning clamping device.
Background technology
In recent years, passenger vehicle high speed, wagon heavy duty demand for development, to iron nitride films performance particularly bogie dynamic performance have higher requirement.The performance parameter of bogie mainly contain one be, two longitudinal, vertical, the horizontal rigidity being, flywheel moment, heights of C.G. etc., the coupling of these parameters decides the quality of bogie performance, therefore, value significant to the development of parameter of bogie test board.
During truck parameter measuring, the framework location of bogie is very important link, if framework is not located in certain direction, then can not measure the party's stiffness parameters upwards; If framework is located inaccurate in some directions, then measuring accuracy can be caused to decline, produce measuring error.At present, the locator meams of framework can be divided into two kinds, namely takes turns and fixes fixing or framework.Utilize wheel to fixed form, during test, framework exerted a force, make to produce relative displacement between framework and bogie, but this fixed form cannot to distinguish one be and the stiffness parameters of secondary suspension to carry out the measurement of bogie integral stiffness parameter.Utilize framework fixed form, if during test to wheel to or wheel shaft force, realize wheel can to measure single stage suspension stiffness parameters to the movement relative to framework; If to car body or simulated frame force, realize car body and can measure relative to the movement of framework the stiffness parameters that two are suspension.In rail vehicle truck comprehensive parameter measuring, usually adopt second method, this just requires that testing table can carry out fixing fast, accurately, easily and reliably to bogie frame.
While mensuration rail vehicle truck parameter, require to can be good at fixing bogie frame, so that can its performance parameter of mensuration accurately and fast, for the sizing of bogie new car and performance test provide condition.At present, the kind model of rail vehicle is various, and existing parameter of bogie test board can not provide the bogie device for positioning and supporting of versatility, wastes human and material resources, importantly can not obtain real data in parametric measurement experiment.Through retrieval, all there is the above-mentioned problem about framework location in current existing parameter of bogie platform, similar techniques is as follows when testing.
