COMPUTATION OF DYNAMIC CHARACTERISTICS OF BOILER WALL IN LARGE POWER PLANT - AN APPLICATION OF DYNAMIC SUBSTRUCTURE SYNTHESIS COMBINED WITH WEIGHTED RESIDUAL METHOD

摘要

In the paper, the dynamic substructure synthesis combined with weighted residual method, offered in [1], is used to determine the dynamic characteristics of boiler walls in large power plants. The number of degrees of freedom to be treated is far less than that in FEM, the amount of input data needed in computation decreases to a great extent, while the results' accuracy is nearly the same as when the large current program SAPS is employed.
