Application of asymmetric eigenvalue method for dynamic analysis of aqueducts

摘要

Taking into consideration of the boundary conditions in fluid-solid interactions,the author built the FSI large rectangle aqueduct model of dynamic analysis according to the equation dynamic performance of the fluid-solid coupling system.Large aqueduct of the dynamic properties were analyzed with asymmetric eigenvalue method,dynamic properties rules were calculated by changing the depth of the water in the aqueduct.
