Aerospace Instrument-Making Annotation << Back TEST RIGS FOR DETERMINATION OF MASS, MASS CENTRE COORDINATES AND INERTIA MOMENTS OF OBJECTS V.V. Bogdanov, V.V. Petronevich, I.N. Panchenko, A.A. Kulikov, V.V. Lyutov, A.Yu. Bugrov, V.S. Manvelyan The article is about the development of methodologies, algorithms and test rigs for measurement of static-dynamic characteristics of physical objects. Solving the task of managing the velocity movement of objects requires its static-dynamic characteristics – mass, mass centre coordinates and inertia moments (tensor). This task is important for aviation, space, missile, shipbuilding industry and other fi elds of science and technique. Information about static-dynamic characteristics is needed during the processes of design, manufacturing and fl utter testing of the dynamically similar models and their components as well as while projecting and manufacturing the dynamic test rigs. Original schemes, methodologies and algorithms for measuring static-dynamic characteristics (mass, mass centre coordinates and central inertia moments) of physical objects are developed. Automated test rigs which provide a single mount measurement of seven static-dynamic characteristics of objects are developed and created. The static characteristics are mass, three mass centre coordinates and three central inertia moments. The measurement results processing is performed in real time. The time of performing tests including the protocol issuance takes 1…2 hours. Keywords: mass, mass centre, mass centre coordinates, inertia moments, inertia tensor, load cell.
