THE MEASUREMENT OF THE PENDULUM DAMPING EFFECT IN SOLID DENSITY SYSTEM
International Journal of Modern Physics: Conference Series(2013)
Abstract
The magnetic damping structure was used in measuring the gravitational constant G by torsion balance. The main purpose is to reduce the effect of pendulum vibration modes. This effect can affect the position of torsion balance. When we use the method A mentioned in OIML R111 to measure density, the pendulum vibration modes of the hanging pan will also be found. In this paper, we will try to introduce the magnetic damping structure to be used on the hanging pan and will present the results of density measurement with the magnetic damper used.
