对扭摆式刚体转动惯量测量仪载物装置的改进

Improvement on loading device of torsion pendulum type rigid body inertia measuring instrument

在应用扭摆式刚体转动惯量测量仪测量刚体的转动惯量实验中,测量球体、圆柱(筒)体和细杆时需要更换不同的夹具,实验操做繁琐.为此设计了固定在仪器中心轴上的综合载物盘,避免了各种夹具的更换,消除了系统误差,提高了测量精度.

A comprehensive loading plate fixed on center shaft was designed to avoid the trequent changes between different fixtures for different rigid bodies, ball, cylinder or slender rod, while measuring the rotational inertia of rigid body in the torsion pendulum type rigid body inertia measuring experiment. The system error caused by the fixture was theoretically eliminate, and the accuracy of measuring results was ensured.
