圆柱体质心测量中转角取值分析

Analysis of the Rotation Angle in Measuring Mass Center of Circular Column

为获得质量非均匀圆柱体质心的三维坐标,测量时需使圆柱体转过一定的角度。分析表明,转角最好取为90度以获得最佳测量效果。如果受条件限制,宜在45度到90度之间选取,尽量避免取小于30度的值。

To obtain three coordinates of mass center of circular column with nonuniform mass distribution, it is necessary to have the cyclic body rotate and angle when measuring. Analysis shows that the value of the rotation angle should be 90 degree for the best measurement. If limited by condition, it should be chosen between 45 and 90 degree. Angle less than 30 degree should be avoided as possible.
