Developed Metro Bogie Dynamic Test System Based on Labview7.1
The first systematic hookup of the metro bogie adopt cone folds a spring coil of the layer rubber, It not only pay to accept the spring coil up the quantity, but also deliver the horizontal force and vertical force of the railroad train, make to shear to slice and squeeze to transform small at the same time, the it damping is press by the liquid to reduce to flap the machine creation, before pack the car must carry on the dynamic state test, otherwise have to dismantle to unload the adjustment again and again, time-consuming hard to tackle. However the first systematic hookup of the metro bogie dynamic state responds time only has 1 second or so, thus short time, the common data collects card is hard to collect 8 displacements and 4 pressurizes. The PXI total line of the National Instruments (NI) company measures to control the system is the main that we adopt to control the instrument, It include: 8 of B PXI-1000 type, inside put the data of PXI-6070 E to collect the card, its function contains 16 road lists to carry/8 roads differential imitate the quantity importation separately, the 12 Bit accuracy, sample velocity 1.25 MS/s,That system satisfies the dynamic state test request. We adopted the graphic programming language to complete at exert to arouse to invigorate under motive of collect the mission, that mission includes the dynamic measuring metro bogie wheel pair four verticals and four horizontals displacement and four vertical force of mission.
