Double-blade lever type barycenter measuring device and measuring method thereof

Abstract

The invention provides a double-blade lever type barycenter measuring device and a measuring method thereof. The measuring device comprises a frame cover and a barycenter measuring instrument arranged in the frame cover, wherein the barycenter measuring instrument comprises a cross beam, a support blade, a working blade, a support pillar, a support beam and an assembling clamp, wherein the support pillar and the support beam are successively arranged under the cross beam; the upper end of the support blade is connected with the cross beam; the support blade is located on the middle parts of the support pillar and the support beam; the lower end of the support blade is connected with the bottom of the frame cover through a projection screen; a pointer is arranged under the support blade; the working blade and the assembling clamp are respectively arranged at the two ends of the cross beam; a scale is hung at the lower end of the working blade through a lifting lug; an electronic balance is jointed on the side of the projection screen, opposite to the scale. According to the measuring method, on the basis of a lever balancing principle, a standard block is selected for accurately measuring the plane of the barycenter of an irregular object, so that the mounting of the engine blade is benefited.

Description

technical field [0001] The invention belongs to the technical field of testing and testing, and in particular relates to a double-knife-edge lever type center-of-mass measuring device and a measuring method thereof. Background technique [0002] The center of mass is the center of mass of the object, and it is also the center of gravity when the gravitational field is uniform. It is an important parameter that needs to be accurately measured in many engineering fields. For high-speed rotating objects, the center of mass is very important, so it is urgently needed A high-precision and general-purpose instrument for determining the position of the center of mass of an object. The centroid measurement devices currently on the market usually have specific applications. When meeting specific measurement requirements, there are often problems such as too large measurement range or insufficient measurement accuracy, and the structure of the measuring instrument system is relatively...
