Research on flexible measurement technology of mass and centroid of rolling ring

Abstract The mass and centroid of rolling rings are the key factors affecting the mass and centroid detection of large launch vehicles. However, at present, the detection of rolling ring mass and centroid stays in the use of theoretical parameters or specially designed measuring tables, and the method used is time-consuming and laborious, and the compatibility is poor. To solve this problem, this paper proposes a flexible measurement method for rolling ring mass and centroid. This method does not need a special measuring platform and has the characteristics of strong universality and high precision. Finally, the feasibility of this method is verified by experiments.
