多跨U形管固有频率的计算
Calculation of the Natural Frequencies for Multiply Supported U -Tube
摘要
Abstract
This paper has done rounded analysis for parameters that have influence on the frequency con-stant of U - tube,based on the finite element analysis of ANSYS software. The result shows that the cal-culation method based on the multiply supported U - tube with ends fixed conform to practical applica-tion. The spans number and end span length has a considerable influence on frequency in some condi-tion. A U - tube system of certain parameter can be calculated as a straight tube system. At the end ob-tains more accurate frequency constant maps and approximate calculation method which would help for the dynamic analysis and safety design of the tube vibration in U - tube heat exchangers.关键词
