高灵敏度振动子最佳阻尼的试验方法

Experimentation Method of the Best Damp Ratio of High-delicacy Bob of Beam Oscillograph

通过建立振子的力学模型及振子的动力学微分方程 ,介绍了确定最佳外接电阻的试验方法 .该方法保证了振子的最佳阻尼 。

The experimental method that makes best outer meeting resistance certain through the establishment of mechanics model and kinetic differential equation of bob is introduced in this thesis. The method ensures bob the best damp ratio and enhances its kinetic measurement precision.
