High-Precision Moment of Inertia Testing System and Error Analysis
Pointed at low precision of great object’s moment of inertia, high-precision moment of inertia testing system is developed. Comparing with several measurement methods, we adopt method of torsion pendulum. We design mechanical structure and analyze error which is compensated in software. According to our experiment, precision of this system can achieve 5‰.
