Research on the Device of Measuring the Centre of a Weight

Abstract

Abstract In order to correct the influence on precision mass measurement caused by the difference between centres of the test weight and the reference weight, the centre of the weight need to be measured, and a device is developed to locate the centre of the weight which includes a balance, a bridge and a supporting pole. In this paper, the detailed force analysis of this device is studied, and the detailed information on designing and selecting each part of the device is given.
