摘要
通过算例就如何应用GB15 1— 1999推荐的非等跨直管固有频率的计算方法进行了较详细的说明 ,提出了简便的手算方法 ,在此基础上还就如何用计算机辅助计算作了简介。
The theoretical analysis of the natural frequency calculation of multi-span tube by national code GB151-1999'Tubular Heat Exchanger' was made and the calculation process was explained in detail.Through an example of natural frequency calculation of multi-span tube in a usual heat exchanger,a convenient method and the computer-aided calculation were presented.It was shown that the result of the convenient method was cosistent with that of the computer-aided calculatio and all results had high precision.
