【摘要】：针对现有转动惯量测量装置中存在测量范围过小的问题,基于扭摆法研制了一台三扭杆测量装置。该装置通过两个可动插销实现单、双和三扭杆的切换,在一台装置上实现三台不同测量装置的功能。同时给出三种不同使用状态下的转动惯量测量范围的详细推导过程。结果表明与单、双扭杆测量装置相比,该装置的转动惯量测量范围明显提高,有效地解决了单、双扭杆存在的测量范围过小的问题,从而验证了该装置的有效性和实用性。
[Abstract]:A three-torsion bar measuring device based on torsion pendulum method is developed to solve the problem of too small measuring range in the existing rotary inertia measuring device. The device realizes the switching of single, double and three torsion rods through two movable pins, and realizes the functions of three different measuring devices on one device. At the same time, the detailed derivation process of measuring range of moment of inertia in three different states is given. The results show that compared with single and double torsion bar measuring devices, the measuring range of inertia of this device is obviously increased, which effectively solves the problem that the measuring range of single and double torsion rods is too small, thus validating the validity and practicability of the device.
