A vibration suppression device using discontinuous spring characteristics was applied to a practical vertical two-drum type washing machine. The effect of this device was investigated by experiments. By investigating various conditions, a most appropriate type was Sound. Analytical model was derived from this experimental set-up and the results of theoretical analysis was compared with the experimental results were compared- Steady-state operation and nonstationary oscillation with a constant acceleration are compared. As the results, the proposed method was effective.Next, a ball balancer was used together with the above mentioned device with discontinuous spring characteristics. Discontinuous spring characteristics is effective to eliminate resonance and a ball balancer is effective to suppress vibrations above the major critical speed.This method was also investigated by experiments. It was verified that the amplitude at the main resonance are suppressed to a specified level and the amplitude became almost zero in the post critical speed range as expected effect.

介绍了一种利用非连续弹簧特性的振动抑制装置在立式双滚筒洗衣机中的应用。通过实验研究了该装置的效果。通过考察各种条件，最合适的类型是声音。分析模型来自这个实验装置和理论分析的结果进行了比较与实验结果进行了比较-稳态操作和非平稳振荡与恒定加速度进行了比较。结果表明，该方法是有效的。其次，球平衡器与上述装置具有不连续的弹簧特性。采用不连续弹簧特性消除共振，采用球式平衡器抑制大临界转速以上的振动，并进行了实验研究。结果表明，主共振处的振幅被抑制到指定水平，并且在后临界转速范围内振幅几乎为零，达到了预期效果。
