本文讨论了压电陶瓷和金属构成的三层复合薄圆板的等效电路和粘接面上的剪应力分布。利用电压策动下强迫振动的稳态解求出系统的纯弹性能,纯电能和机电耦合能。再用推导等效电路的能量法求得系统的四端等效电路。在无损耗的情况下,该等效电路在所有的频率上都是正确的。然后利用等效电路求出共振频率附近的有损耗存在的位移函数。再由运动微分方程就可得到动态剪应力的分布。剪应力与策动电压和机械品质因数的乘积成正比。圆板中心处的剪应力为零。随着半径的增加剪应力迅速增加。当r/a=0.85时,剪应力有极大值,边缘上的应力略有下降。

Forced longitudinal vibration of a drill string is the most important one in its three kinds of vibration. This paper sets up a general model of forced longitudinal vibration to approximate more closely the real situation. This model is suitable for any drill string assembly. The analysis of all kinds of energy loss leads to the formulas for computing the damping factor of longitudinal vibration of a drill string. On the basis of the characteristics of forced longitudinal vibration, the paper suggests a new concept of generalized state vector, which enables us to describe the vibration of a drill string. The generalized transfer matrix method is used to compute the forced longitudinal vibration, thus eliminating the need of analytical solution. The generalized formulas used for computing the steady-state response of forced longitudinal vibration of any drill string assembly is given, and appropriate ways for computing the state vector under different measurement conditions are proposed.

钻柱纵向受迫振动的研究在钻柱的三种振动形态中最为重要。本文建立了能更真实反映钻柱系统的纵向受迫振动模型,此模型适合于任意组合钻柱。分析钻柱各种能量损耗后,给出钻柱纵向振动时的阻尼系数计算公式。根据钻柱纵向受迫振动的特点,本文提出广义状态向量的新概念,并且用此向量描述钻柱的振动状态。用广义传递矩阵方法研究钻柱纵向受迫振动的一般规律,克服了直接求问题的解析解存在的困难。文章给出计算任意组合钻柱系统的纵向受迫振动的稳态响应的一般公式和不同测量条件下求状态向量的不同途径。
