摘要
本文根据控制壳体自由弯曲振动的Von Kármán动力方程,采用加权余量法得出了一种分析正交各向异性圆柱层壳自由振动的新方法。结果与Werner Soedal的结论吻合良好。文中将该方法用于数值计算,并通过比较三种管子的自振频率验证了方法的有效性。
Based on the dynamic Von Karman-type equations governing the free flexural vibration of the shell, the weighted residual method is adopted in this paper to have otained a new method for the free vibration analysis of the orthotropic circular cylindrical shell of laminated composite. The result obtained is in good agreement with that of Werner Soedal's method. In this paper,the method is applied to the numerical calculations, and its validity is verified by comparing the natural frequencies in three types of pipes.
