【Abstract】 With the help of a large sized finite element general program MSC/NASTRAN the dynamic characteristics of the shrouded blades of a steam turbine are studied and the treatment of boundary conditions, the "tenseness" between shrouds as well as the load bearing conditions of the blades discussed. In addition, the analysis of a specific example is conducted to expound the above cited points.更多还原
