摘要
通过解微分方程和微分等数学手段,给出了滑块通过平衡位置的速度与阻尼因数之间的关系,并利用Origin软件对实验数据进行直线拟合,从而确定振动系统的阻尼因数及其他振动参数.该测量方法容易操作,实验数据易得、可靠且处理简单.
In this paper,the relationship between the slider＇ s velocity in balancing position and the damping coefficient was obtained through solving differential equations and differential.A linear fit was then applied to the experimental data by using the origin software,and the damping coefficient was determined including other vibration parameters.The method was easy to operate,and the experimental data is easy to be obtained and reliable,and the processing of the experimental data is very simple.
