Analyst the Inherent Characteristic of the General Support Pipeline with DQ Method Based on Matlab Programming
The Differential Quadrature Method（abbreviated as DQM）is easy to be implemented by computers to solve many problems in engineering mechanics. In the field of pipe vibration methods are mainly finite element method , finite difference calculus and so on. In the formation of coefficient matrix these methods need to calculate a large number of numerical integration , resulting in low efficiency, while we can use matlab to program, taking the advantage of easy programming of DQM, after establishing mathematical model of the pipe conveying fluid .The program designed in this paper can be a very good solution to pipe nature frequency.After obtaining the nature frequency, we have analyzed the relationship between pipe length and nature frequency and have found out the critical value of the pipe length. The method can also be applied to engineering filed related .
