Abstract: In order to ensure accurate control and effective operation of payload, the mass trim mechanism is used in adjusting mass properties precisely, which features low cost, small in volume and weight, long service life, and high reliability. This paper reviews the concept and schemes of the mass trim mechanism, together with its applications and recent development, and discusses some key technologies related to this mechanism. At the end, some prospective applications of mass trim mechanism in our country’s space explorations are suggested.
