从理论上分析了垂直振动的产生原因及其与钻进参数的关系．在此基础上，应用模糊控制理论，提出了垂直振动超限时改进的一维模糊控制方法及控制策略，并在牙钻机实验台上进行了控制实验．结果表明，当垂直振动超限时，该控制方法可使其迅速降至设定值附近；当垂直振动小于设定值很多时，钻进参数会自动提高，以保证钻进效率． The reason of vertical vibration and its relationship with drilling parameters are theoretically analyzed. On the basis of this, the application of fuzzy control theory is proposed to improve the one-dimensional fuzzy control method and control strategy when the vertical vibration exceeds the limit, and the control experiment is carried out on the dental drill bench. The results show that when the vertical vibration exceeds the limit, the control method can quickly reduce it to the set value. When the vertical vibration is less than the set value, the drilling parameters will be automatically increased to ensure the drilling efficiency.
