建立了动调陀螺轴向振动力学模型,并根据仪表的具体结构,设计了两种不同结构形式的吸振器以用于动调陀螺的抑制。理论和实验数据表明,在动调陀螺轴系上附加有阻尼的动力吸振器,可以大幅度地降低仪表谐振时的振动放大量级,改善仪表的振动特性,提高其抗随机振动能力。
Based on the specific structure of the instrument, two kinds of vibration absorbers with different structures were designed for the suppression of the gyroscopic gyroscope. The theoretical and experimental data show that the addition of a damped dynamic vibration absorber on the spindle can greatly reduce the magnitude of vibration amplification during instrument resonance, improve the vibration characteristics of the instrument and enhance its resistance to random vibration.
