摘　　要：首次提出对柔性连杆机构振动采用主被动混合控制的方法。导出了粘贴压电材料和粘弹性材料的构件的有限元方程，应用常增益微分控制器对柔性机构振动主被动控制方法进行了分析研究。讨论了粘弹性材料层的厚度对控制输入和控制效果的影响，最后对一柔性机构振动响应的控制进行了计算机仿真，证明了本文方法的有效性。The method of active passive vibration hybrid control for flexible mechanisms is proposed for the first time.The FEM equation of flexible mechanisms with boned piezoelectric material and viscoelastic material is derived.Using the constant gain feedback controller,the relations of the thickness of viscoelastic material layer with the control input voltage and the control effect are studied.And it is shown that,in general,the active passive hybrid control method provides more suppression of flexible mechanisms peak vibration amplitudes than those of the purely active control method and the purely passive control method.Finally,a numerical simulation is performed to evaluate the improvement of elastodynamics response of a four bar mechanisms.
