Mass measurement system and method using inertial force and standard mass in gravity-free environment

摘要

The present invention relates to a mass measurement system and method using inertial force and standard mass in a gravity-free environment. The mass measurement system includes a linear acceleration motion unit that is a linear motion driving source, a first load cell fastened to the linear acceleration motion unit to measure an inertial force of a sample caused by linearly accelerated motion of the linear acceleration motion unit, a second load cell fastened to the linear acceleration motion unit while being spaced apart from the first load cell by a predetermined distance, the second load cell measuring an inertial force of a standard sample having a known standard mass caused by the linearly accelerated motion of the linear acceleration motion unit, and a main control unit for calculating and outputting mass of the sample through an arithmetic operation based on the inertial forces, measured by the first and second load cells, and the standard mass, and controlling an entire operation of the system. Accordingly, the present invention is advantageous in that it can precisely measure the mass of a sample having a small mass using a simple construction.
