| Abstract: | This paper discussed some problem encountered in calculation of gas column natural frequency based on the frequency response function method. The improvement in consideration of modeling numerical method is put forward. A new root verification process is imported in the calculation. Compared with the experiment, old method, and used in practical piping calculation the result shows that the improved method is very satisfactory and efficient. |
