许多不规则非均质复杂构件的重心位置很难精确计算,需要用实验方法确定。不同质量和形状的复杂构件相应用不同的方法和设备测定。对于某些小型粗短的轴对称构件,像小型导弹、炮弹等,则常常要求测量成品件的重心偏离其轴线的距离和方法,采用天平式下卧径向偏心仪能比较简便地测出。 Many irregular heterogeneous complex components of the center of gravity position is difficult to accurately calculate the need to experimentally determine. Different quality and shape of the complex components corresponding to different methods and equipment determination. For some small stubby axisymmetric components, such as small missiles, shells, etc., it is often required to measure the distance and the method of center of gravity of the finished part deviating from its axis, which can be measured relatively easily using the balancer radial subscenter.
