圆柱体质量、质心和质偏测试方法及误差分析

Testing Method of Mass,Centroid and Centroidal Deviation of Cylinder and Error Analysis

提出了3种圆柱体质量、质心和质偏测量方案,即4点式测量、轴径3点式测量和轴周3点式测量。针对其中的4点式测量方式又提出了2种测试方法,并比较了2种测试方法的误差;通过理论推导,对3种测试方案引起的质偏误差进行了优劣论证。

Firstly,this paper put forward three testing schence, for cylinder＇s mass,centroid and centroidal deviation,which were 4- point measurement ,axial 5-point measurement and radial 3-point measurement. Then ,it put emphasis on 4-point measurement,and proposed two approaches based on 4-point measurement. Finally,the testing errors were analyzed theoretically.
