许多不规则非均质复杂构件的重心位置很难精确计算求得,需用实验方法测定。不同质量和形状的构件相应要用不同的方法和设备测定。某些中小型粗短轴对称构件,如小型导弹、炮弹等,要求测其重心相对于中心轴线的偏移位置,若用天平式径向偏心仪进行测量,就比较简便、准确。为此本文介绍一下这种偏心仪。 Many irregular heterogeneous complex components of the center of gravity is difficult to accurately calculate the location, the need for experimental determination. Different quality and shape of the components corresponding to the use of different methods and equipment determination. Some small and medium-sized stubby axial symmetric components, such as small missiles, artillery shells and other requirements of the center of gravity measured relative to the central axis of the offset position, if using a radial balancer to measure the balance, it is relatively simple and accurate. This article describes this eccentric.
