Design and Verification of Angular Momentum Balancing Mechanism of Remote Sensing Camera Posture Control Axis
摘要
Abstract
In the occasion that more than one remote sensing cameras were installed on one remote sensing satellite,reaction and angular momentum would be produced by adjusting certain remote sensing camera.This reaction and angular momentum would change the posture of remote sensing sat-ellite,and then influence the posture of other remote sensing cameras.An angular momentum balan-cing mechanism was designed to balance the angular momentum in posture control axis of remote sensing camera.This angular momentum balancing mechanism was composed of a motor,a principal axis,a gear system,a gear speeder and an angular momentum balance wheel.In the mechanism,the principal axis was driven by the motor rotor,the principal axis drives the posture control axis of re-mote sensing camera,meanwhile,the reaction of the motor stator drives the gear system and rotates the angular momentum balance wheel via the gear speeder.The angular momentum could be calculat-ed by adjusting the quality amplification coefficient of the angular momentum balance wheel or the speed increasing ratio of the gear speeder.Thus,the angular momentum internal self-balancing can be realized.Then,the correctness of mechanism design was proved by the principle of angular momen-tum conservation and the basic principles of theoretical mechanics.Finally,a three-dimensional dy-namic simulation model of the mechanism was established and the simulation parameters of the mech-anism were set according to the actual parameters of the mechanism.Simulations were carried out with given load and results are analyzed.The feasibility of the mechanism design is further validated.关键词
