A method and system for measuring the distance of an aircraft from a stress point on the ground

Abstract

The invention discloses a method of measuring a distance between ground force bearing points of a plane and a system. The plane is drawn on three weighing platforms, and positions of force applying points on the weighing platforms can be conveniently and accurately measured by adopting a torque balancing principle. The advantage that force borne by four weighing sensors on each weighing platform can be independently outputted is used, the torque balancing principle is adopted, the positions of force applying points on the weighing platforms can be conveniently and accurately measured, distances between ground force bearing points of the plane measured by the method are the positions of ground actual force applying points, the fact that the traditional length measurement tool such as a tape measure is used for measuring the connection line length of plane wheel geometric center points rather than the ground actual applying points of the plane wheels, and thus the plane gravity center measurement result is influenced can be avoided, the method provides accurate distance parameters for calculating the gravity center of the plane, and the calculated plane gravity center data can be ensured to be accurate and reliable.

Description

【Technical field】 [0001] The invention belongs to the fields of aircraft ground support and aircraft weighing, and in particular relates to a method and system for measuring the distance of an aircraft on a ground stress point. 【Background technique】 [0002] The aircraft weighing system develops with the development of digital intelligent load cells and intelligent digital weighing systems. Although measuring the distance of the aircraft's stress point on the ground has changed from the traditional tape measure to the current high-precision and high-cost laser three-dimensional measurement, no matter how accurate the measured data is, the result is only the line connecting the geometric center points of the aircraft wheels Length, rather than the length of the line connecting the actual force point when the aircraft wheel acts on the ground (or the weighing platform), this will inevitably affect the measurement result of the aircraft center of gravity. 【Content of inventi...
