摘要
传递矩阵法是计算输流管路流固耦合最常用、最有效的计算方法之一;但其算法精度将直接影响最终的求解结果的准确性。本文以Timoshenko梁模型为理论基础,推导出场传递矩阵,并对其采用不同的数值算法。结果表明,与其他数值计算方法相比,精细积分法具有更高的精度及效率。
Transfer matrix method is one of the most common and efficient method to calculate the fluid-structure interaction behavior of pipes conveying fluid.And the accuracy of algorithm will directly affects the accuracy of the final solutions.In this paper,the field transfer matrix will be deduced from Timoshenko beam theory with different numerical calculations.It is found that the precise integration for transfer matrix method had advantages of saving time and obtaining accurate results in contrast with other numerical methods.
