Device and method for measuring mass center

The invention provides a device for measuring the mass center of mass. The device comprises a tool clamp; the static balance measuring and adjusting table is connected with the tool clamp and is used for bearing a product to be measured and carrying out rotary static balance measuring operation; the input end of the data acquisition system is connected with the output end of the static balance measurement and adjustment platform, and the data acquisition system is used for acquiring data measured by the static balance measurement and adjustment platform; and the standard body is connected with the static balance measurement and adjustment platform and is used for calibrating and calibrating the static balance measurement and adjustment platform. According to the method, the problem of low measurement precision is solved, the quality, the three-dimensional mass center and the static unbalance amount of solid attitude and orbit control system products are measured and tested on the basis of a rotation method ma
