Abstract
An apparatus and method for measuring a structural angular acceleration based on dynamic centrifugal force measurement belong to the technical field of angular acceleration measurement. The apparatus has a solid ball. The solid ball can move freely along the radial direction of the outer wall packaging hood. The elastic block is used as a stress base. A rod for lateral limit and connection is used for connecting the rigid block and a pulley and limiting the displacement of solid ball so that the solid ball can only move longitudinally along the apparatus. The rigid block can move freely due to the pulley. Measurement of a transient angular acceleration is converted into dynamic measurement of the centrifugal force of the solid ball. Through the above design, the dynamic angular acceleration of the structure caused by dynamic load can be relatively accurately calculated.
