Abstract:A new dynamic grids method is presented by using temperature analogy. The displacement of the moving boundary is considered as temperature boundary conditions, the internal nodes’ displacement is obtained by solving energy equation or heat conduction equation. The temperature analogy is used to solve fluid-structural interaction problem. Examples include forced vibration of a thin cambered blade and vortex induced free vibration of cylinder. Compared with other methods, the temperature analogy is more efficient and robust. The results show the temperature analogy can effectively solve the dynamic grids problems in the vibration engineering.
