Abstract

The embodiment of the invention discloses a step torque loading system and a step torque loading method. The system comprises two step force loading devices; and a loading tool positioned between the two step force loading devices; the two step force loading devices are respectively connected with the loading tool through magnetic cushion blocks; each step force loading device comprises a base; a torque loading assembly assembled on the base through a lifting rod; and an electromagnet which is connected with the torque loading assembly through a loading rod; the torque loading assembly comprises a mounting seat, a tension-compression spring positioned in the mounting seat, a torsion handle connected to one end of the tension-compression spring, and a horizontal beam connected to one end, far away from the torsion handle, of the tension-compression spring; and the axis of the tension-compression spring is perpendicular to the axis of the lifting rod. According to the system, the problem of loading time difference of two sets of step force loading devices caused by manual cutting or burnout of a flexible wire in the prior art can be avoided.

Description

technical field [0001] The invention relates to the field of satellite disturbance characteristic measurement. More specifically, it relates to a step torque loading system and method thereof. Background technique [0002] The disturbance torque induced by the satellite's digital transmission antenna and the sun wing drive mechanism and other rotating parts during normal operation will have an impact on the pointing accuracy and imaging quality of the satellite. It is necessary to obtain the disturbance torque characteristics of the rotating part through ground test measurements. The satellite's disturbance rejection design provides input. The piezoelectric disturbance torque measurement platform has been widely used in the field of satellite disturbance characteristic measurement due to its advantages of high rigidity and good medium and high frequency performance. Low-frequency performance is not good, let alone static measurement. [0003] Considering that the magnitud...
