Abstract

The embodiments of the invention provide a symmetrical combination gravity center measuring device and method. The symmetrical combination gravity center measuring device comprises a base, a bearing,a rotating shaft, a storage plate, a balance body, positioning pins, a pulling rope fixing shaft, a pulling rope, an electronic forcemeter and a level; the base and the rotating shaft are connected through the bearing, the storage plate and the rotating shaft are fixed into a whole, and the level is mounted on the storage plate; the pulling rope fixing shaft is mounted on one side of the storage plate, the center line of the pulling rope fixing shaft is parallel to the center line of the rotating shaft, and the distance between the center line of the pulling rope fixing shaft and the upper surface of the storage plate is equal to the distance between the center line of the rotating shaft and the upper surface of the storage plate; the electronic forcemeter is connected with the pulling rope fixing shaft through the pulling rope, and the balance body and the two positioning pins are both mounted on the other side of the storage plate; and the center lines of the two positioning pins areperpendicular to the upper surface of the storage plate, and the plane constituted by the center lines of the two positioning pins is parallel to the center line of the rotating shaft. The symmetrical combination gravity center measuring device is simple in structure, a plurality of sensors do not need to be mounted, operation, observation and data processing are convenient, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of center-of-gravity measurement, and in particular relates to a symmetrically combined center-of-gravity measuring device and method. Background technique [0002] The shape of the aircraft or its component systems is mostly a symmetrical combination. It is often necessary to measure the center of gravity at each stage of the development of the aircraft or its component systems. Most of the existing center of gravity measurement devices and measurement methods use the principle of multi-point weighing, mainly divided into three-point weighing. Weight, four-point weighing, and four-point or more weighing require multiple sensors to be installed in different parts of the object to measure simultaneously, and the center of gravity can only be calculated after comprehensive processing of the measurement data of multiple sensors. The measuring device is complex in structure, high in cost, large in measurement da...
