    摘要:

    針對蛋品運(yùn)輸多維隔振裝置阻尼的設(shè)計問題,，指出按單自由度隔振系統(tǒng)經(jīng)典幅頻特性圖確定阻尼系數(shù)不合理,，而應(yīng)按“二階系統(tǒng)瞬態(tài)響應(yīng)性能指標(biāo)”理論確定該多維隔振裝置的阻尼系數(shù),，并進(jìn)行了相關(guān)計算,。利用數(shù)控車床測定了所用氣缸阻尼器的阻尼系數(shù)。通過仿真和實驗,，對比了阻尼比分別為0.100和0.707時的上平臺加速度,。結(jié)果表明，當(dāng)采用最佳阻尼比0.707確定氣缸阻尼器的阻尼系數(shù)時,，蛋品運(yùn)輸多維隔振裝置隔振效果良好,。

    Abstract:

    Damping of a multidimensional vibration isolation device for transporting eggs was discussed. The air cylinder was used as a damper and its coefficient of damping was measured with CNC lathe. The accelerations of up-platform with different coefficients of damping were measured and compared by means of ADAMS simulation and experiments. Studies indicated that it’s inappropriate to design the damping of the device according to the classic amplitude-frequency chart. It was proposed that the damping should be decided according to performance index of transient response of second order system. The conclusion showed that the multidimensional vibration isolation device for transporting eggs isolates vibration present a favorable effect when the damping ratio of 0.707 is adopted for the coefficientof damping of the air cylinder. 
