Object centroid testing method

Abstract

The invention provides an object centroid testing method. The object centroid testing method includes that a test bench comprising a main unit and a bundling component is provided, the main unit comprises a base, a swing component, a slide component, a rotating component and an overturning component, and the swing component, the slide component, the rotating component and the overturning component are fixed on the base; the swing component comprises a swing disc capable of freely swinging back and forth; the slide component comprises a slide disc arranged on the swing disc and capable of sliding back and forth relative to the swing disc; the rotating component comprises a rotating disc which is arranged on the slide disc and capable of horizontally rotating on the surface of the slide disc; the overturning component comprises an overturning disc arranged on the rotating disc and capable of overturning leftwards and rightwards relative to the rotating disc; the bundling component is arranged on the overturning disc and used for fixing an object to be tested. The test bench further comprises a measuring tool and an angle gauge, wherein the measuring tool is used for measuring the sliding distance of the slide disc and the angle gauge is used for measuring the oblique angle of the swing disc. By measuring the centroid of the object to be tested via the test bench, the centroid of the object to be tested is obtained. The object testing method is high in accuracy, simple and short in measuring time.

Description

technical field [0001] The invention relates to a method for testing the center of mass of an object. Background technique [0002] In the prior art, there are mainly three methods for measuring the center of mass of an object: the three-wire pendulum method, the torsional pendulum method and the compound pendulum method. Among them, the three-line pendulum method for measuring the center of mass of the measured object has the advantage of simple equipment, but the disadvantages are that its measurement accuracy is low, the installation of the tested object is time-consuming and laborious, and the test period is long. The principles of the torsion pendulum method and the compound pendulum method are basically the same, but the test bench measured by the torsion pendulum method, the adjustment of the various postures of the measured object on the test bench and the measurement of each relative position are not easy to get a good control, which will give the final measurement ...
