激振器的偏置控制是控制激振器围绕偏离液压执行元件（液压缸或液压马达）平衡位置特定距离振动。提出了一种高频激振的2D阀控电液激振器的偏置控制方法，该方法是将一个数字伺服阀与2D激振阀并联，从而实现振动中心的偏置控制。在并联数字伺服阀开口分别正偏50%，100%和负偏50%，100%的情况下，对激振器低频和高频情况下输出的载荷力变化情况进行了实验研究。实验结果表明：激振器在低频和高频下的偏置量与并联阀口开度成一定关系。该方法旨在实现激振器的振动偏置控制。
激振器的偏置控製是控製激振器圍繞偏離液壓執行元件（液壓缸或液壓馬達）平衡位置特定距離振動。提齣瞭一種高頻激振的2D閥控電液激振器的偏置控製方法，該方法是將一箇數字伺服閥與2D激振閥併聯，從而實現振動中心的偏置控製。在併聯數字伺服閥開口分彆正偏50%，100%和負偏50%，100%的情況下，對激振器低頻和高頻情況下輸齣的載荷力變化情況進行瞭實驗研究。實驗結果錶明：激振器在低頻和高頻下的偏置量與併聯閥口開度成一定關繫。該方法旨在實現激振器的振動偏置控製。

The bias control of exciter is to make the exciter to vibrate around the equilibrium position of the hydrau-lic actuator (hydraulic cylinder or hydraulic motor) from a particular deviation. In order to achieve the bias control of the vibration central position, this paper presents a bias control method of high-frequency excitation of electro-hy-draulic exciter controlled by 2D valve, which the 2D exciting valve is placed in parallel with a digital servo valve. To observe the output load force change of the exciter, we have done experimental research at low and high frequen-cies when the paralleled digital servo valve opens to the positive side 50%, 100% and to the negative side 50%, 100%respectively. The result shows that the offset of the exciter at low and high frequencies is related to the open-ing of the paralleled valve, and that we can achieve the bias control of vibration exciter in this way.
