Abstract

The invention provides a one-dimensional mass center measuring device based on a moment balance principle and a method thereof. A supporting device is arranged on ground. The upper end of the supporting device supports a lever through a main blade. A left lifting mechanism and a right lifting mechanism are used for supporting the lever and realize lever lifting. The left end of the lever is provided with an electromagnetic torquer and a shifter, and the right end is provided with an automatic loading system for loading a counterweight. The counterweight loads a force to the lever through an auxiliary blade. The lever is provided with a product fixing pin for fixing a measured product on a tool. A tool fixing pin is used for fixing the tool on the lever.

Description

technical field [0001] The invention belongs to the field of centroid measurement, and in particular relates to a one-dimensional centroid measurement device and method based on the principle of moment balance. Background technique [0002] The center of mass is one of the important static parameters of the aircraft, which will directly affect the flight attitude of the aircraft, and even affect the hit probability of the system. At present, the center of mass test at home and abroad mainly adopts the multi-point support weighing method. The basic test principle of the multi-support weighing method is to use three or more load cells to jointly support the object to be measured, so that each sensor is stressed, and then calculate the moment based on the position of each sensor relative to the reference center point. This test method is relatively simple, and can measure mass and centroid parameters at the same time. However, due to the limitation of sensor accuracy and instal...
