Simple beam amount of deflection testing arrangement

The utility model relates to a railway territory discloses a simple beam amount of deflection testing arrangement, wherein testing arrangement includes: first, the 2nd displacement sensor are used for the test the simple beam cuts first, the second of area sensor position and indulges the bridge to the displacement, and data processing device, be used for the basis first, second is indulged the bridge and is reached to the displacement vertical height between first, the 2nd displacement sensor draws the corner in simple beam cross -section is in order to obtain the simple beam amount of deflection. This testing arrangement or method can not receive the restriction of topography, hydrologic condition when the test to can eliminate resonance, the wind load influence to the test system.
