Abstract

The invention provides a supporting device with a ball socket, a column socket and a plane combined in mass center measurement and relates to a supporting structure. The problems that a sensor adopted in an existing mass center measurement ball-ball socket supporting method can not be automatically adjusted to the position aligned with a bearing point, accuracy of the alignment position is poor, and guide friction force is large in a ball plane supporting method can be solved. The supporting device comprises a ball socket supporting structure, a ball plane supporting structure and a measurement pedestal and further comprises a column socket supporting structure. The column socket supporting structure comprises a column socket board, a steel ball, a ball base, a bearing sensor, a bearing sensor tray and a base. The bearing sensor is installed on the bearing sensor tray. The bearing sensor tray is rotationally installed on the base. The base is installed on the measurement pedestal. The ball base is detachably installed on the bearing sensor. The steel ball is placed in the middle of the upper surface of the ball base. The horizontally-arranged column socket board is placed on the upper portion of the steel ball. The supporting device is used for large-size aircraft mass center measurement.

Description

technical field [0001] The invention relates to a support structure, in particular to a support structure of large-scale aircraft centroid measurement equipment. Background technique [0002] The support method of large-scale aircraft centroid measurement equipment and the problem of lateral force have always existed, which affect the measurement accuracy. From the basic principle of the multi-point method, it can be known that the output value of the sensor and the measurement value of the position of the force point of the sensor directly affect the measurement result of the mass center of mass, so how to ensure the accuracy of the output value of the sensor and the measurement value of the position of the force point of the sensor center has become an important issue for improvement. The key factor for the measurement accuracy of the centroid of mass measuring platform. The supporting structure of the sensor is a key factor affecting the output characteristics of the sen...
