摘　　要：为减小飞轮控制系统工作时产生的振动影响,采用形状记忆合金被动减振方式构建飞轮控制系统及其动力学模型,对飞轮控制系统被动减振机理进行分析。研究结果表明:基于形状记忆合金被动减振的飞轮控制系统的振幅随着记忆合金弹簧-阻尼结构阻尼的增加而明显减小;在不同频率下,基于记忆合金弹簧-阻尼结构的被动减振飞轮控制系统模型的振动幅值要比非减振飞轮控制系统模型振动幅值降低明显,且具有较好振动衰减效果。In order to reduce the influence of the vibration which appears when the flywheel control system works, the flywheel control system and its dynamic model with shape memory alloy were built in passive vibration damping way, and passive vibration damping mechanism and simulation on flywheel control system were analyzed. The results show that the vibration amplitude of flywheel control system with shape memory alloy in passive vibration damping way obviously reduces with the increase of the damping value of shape memory alloy spring-damping structure. With the increase of different frequencies, the vibration amplitude of flywheel control system model based on shape memory alloy spring-damping structure in passive vibration damping way is obviously lower than that of non-damping flywheel control system model and is of better vibration damping effect.
