摘要

摘要:
随着航天器平台性能指标要求的提高，飞轮微振动对航天器平台的影响越加突出，需要对其进行振动抑制。根据飞轮上壳体的模态特性，提出一种圆环形黏弹性阻尼环结构的设计方法，并针对黏弹性阻尼环的敷设位置、厚度、宽度对其减振效果影响规律进行数值仿真与试验验证，验证圆环形黏弹性阻尼环的有效性。结果表明：圆环形黏弹性阻尼环结构对宽频振动具有良好的减振效果，黏弹性阻尼环的敷设位置对飞轮系统的各阶固有频率变化和减振效果起决定性作用，在飞轮外径的60%处敷设圆环形黏弹性阻尼环减振效果较好，宽度设计为飞轮外径的6%以内、厚度设计为壳体厚度的4倍以内时，随着宽度、厚度的增加，减振效果提高。

Abstract:
As the requirements for performance indicators of spacecraft platforms increase, the influence of micro-vibrations generated by flywheels on spacecraft platforms is becoming increasingly prominent and needs to be suppressed. Based on the modal characteristics of the upper housing of the flywheel, a design method of circular viscoelastic damping ring structure was proposed, and numerical simulations and experiments were carried out to verify the damping effects of the viscoelastic damping ring in terms of the position, thickness, and width and verify the validity of circular viscoelastic damping ring. The results show that the circular viscoelastic damping ring structure has a good damping effect on broadband vibration, and the position of the viscoelastic damping ring plays a decisive role in the change of the inherent frequency of the flywheel system and the damping effect. The damping effect is better when a circular viscoelastic damping ring is applied at 60% of the outer diameter of the flywheel. When the width is designed to be within 6% of the outer diameter of the flywheel, and the thickness is designed to be within 4 times the thickness of the housing, the damping effect increases with the increase in width and thickness.
