       Product of inertia measurement system

Product of inertia of specimen which is of Asymmetric structure can be measured by measuring the moment of inertia via Swing.

as for this moment of inertia measurement System, the fixture is horizontally installed when ly, lz, and lyz are Measured, the fixture is installed at a 45° when Ixy and Ixz are measured, and the Fixture is installed vertically. There are 3 kinds of no-load situations, so it Is necessary to measure the tensor under 3 kinds of no-load conditions and 6 Kinds of load conditions, therefore, the measured tensors are ly under no load, Lx under no load, lxy under no load, ly under load, lz under load, lyz under load, Lxz under load, lxy under load, and lx under load.
