Structure angular acceleration measuring device based on dynamic centrifugal force measurement and method thereof

A structure angular acceleration measuring device based on dynamic centrifugal force measurement and a method thereof belong to the field of angular acceleration measurement technology. The device isinternally provided with a solid sphere. the solid sphere can perform free movement along the radial direction of an outer wall packaging cover. A centrifugal force after movement of the solid sphereis transferred to a flexible block through a rigid block. The flexible block is used as a force bearing matrix. A strain gauge is fixed to the surface of the flexible block for detecting the radial strain of the flexible block. Through a formula, the centrifugal force which is bear by the solid sphere is calculated in structure torsion. A lateral spacing connecting rod is used for connecting the rigid block with a pulley and restricting displacement of the solid sphere so that the solid sphere can only move along the longitudinal direction of the device. A pulley makes the rigid block performfree movement. According to
