New Three Points Measurement of Column Structure's Mass, Centroid and Centroidal Deviation

摘要

In this paper, we brought forward a new measurement----the new three points measurement of column structure’s mass, centroid, and centroidal deviation. The paper discussed the measure principle of the new measurement, it analyzed the merits and flaws of three measurements, and got the conclusion: the new three points measurement have high precision at the centroidal deviation’s measuring, and the method is simple. It can get the three parameters of the column by measuring twice in one state, at the same time, the machining of testing equipment and the debugging both are easy. The method have the merits of three points measurement and four points measurement, it is a kind of applied measurement.
