Embodiment 1
[0057] Embodiment one: a kind of assay method of crane big wheel pressure, comprises the steps:
[0058] (1) Cloth piece: Select the side of the cart track that can ensure that all the wheels of the crane can pass through to paste the strain gauge, and determine the position of the cloth piece, which is generally located in the middle of the adjacent pressure plate;
[0059] Among them, after the resistance strain gauges are pasted on the side of the cart track in such a way that the length direction of the resistance wire is perpendicular to the top surface of the track, the strain gauges are connected by a half-bridge method;
[0060] In this step, the temperature compensation method is used to compensate the strain of the strain gauge caused by the temperature change, and one of the dynamic simulation method and the self-temperature compensation method can be selected.
[0061] In this embodiment, the dynamic simulation method is selected, and the temperature compensation s...
