Two-dimensional centroid measuring device and measuring method thereof

Abstract

The invention discloses a two-dimensional mass center measuring device and a measuring method thereof, and relates to the technical field of instrument measurement. The problem that the mass center of an existing measured object is difficult to measure or low in measurement precision is solved. The device comprises a scale pan, a bottom plate, a clamp, three floating fulcrums and three sensors, the bottom plate is horizontally arranged, the three sensors are uniformly distributed at the upper part of the bottom plate along the circumferential direction of the same circle, the floating fulcrums are arranged above the sensors, the scale pan is erected at the upper ends of the three floating fulcrums, and the clamp is arranged on the scale pan. The device is used for measuring the projection position of the workpiece mass center on the horizontal plane.

Description

technical field

[0001] The invention relates to the technical field of instrument measurement, in particular to a two-dimensional centroid measurement device and a measurement method thereof. Background technique

[0002] With the development of science and technology, more accurate and simpler methods are needed to obtain the mass and center of mass of blades, loads, projectiles and other components in the fields of aviation, aerospace, military industry, and power. At present, the common measurement methods include suspension method, static method and dynamic method, which have the disadvantages of poor precision, low efficiency and high cost. Therefore, it is necessary to develop an accurate and fast new type of center-of-mass measurement equipment to provide new technology and new equipment for mechanical measurement.
