摘要
短索适合用固支轴拉梁模拟而非弦,以固支梁振型函数作为短索近似振型函数,用Rayleigh法推导出任意阶次的短索索力实用计算公式,引入频率阶次参数,近似简化了实用公式,这便于工程应用;分析了简化公式的误差,通过实例表明公式都有较高的精度。
Short cable is suitably simulated by clamp beam with axial tension, rather than taut string. With Rayleigh＇ s method, clamp beam＇ s mode used for short cable＇ s approximate mode, a practical formula is deduced and simplified by order parameters of frequence, considering any order mode. For engineering convenience, the simplify error is discussed and the formulas are verified by example.
