| Abstract: |
| According to the characteristics of aerospace products which have large size and big weight, to meet the demand of mass properties measurement, based on the gas bearing type of the mass properties measuring instruments, this paper introduces a mass properties measuring system which is based on L tooling. Because its level measurement does not need the secondary lifting, it greatly improves the accuracy of measurement and efficiency of measurement. It realizes three-axis measurement of certain products’ center of gravity and moment of inertia. |
| Key words: L tooling the center of gravity the moment of inertia mass properties measurement |
