| Abstract: | 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. |
