  • 摘要: 应用符号计算获得足够高的计算精度来实现固支拉索及吊杆固有振动频率方程的高精度求解和振型函数的数值计算.结合实例计算对比分析了不同边界条件对拉索及吊杆振型的影响.

     

    Abstract: A sufficiently high computational accuracy is achieved by symbolic computation to obtain a high precision solution for the frequency equation and the numerical calculation for mode functions of cables and suspenders fixed at one or two ends. Based on practical examples, the influence of boundary conditions on vibration modes of cables and suspenders is comparatively analyzed.
