RESEARCH ON DYNAMIC SIMILARITY LAW OF FLUID-SOLID INTERACTION MODEL OF THE REACTOR VESSEL

摘要

There is a huge volume of fluid exists in the reactor vessel and oil tank, so in the seismic test on structure, the effect of fluid-solid interaction on structure earthquake response should be in our consideration. The dynamic similarity law employed in the test model of reactor vessel structure is far more complicated than that of solid-only structure model. Based on the seismic test research of Fast Breeder Reactor block model, this paper presents two practical anti-seismic test models of reactor vessel structure: the gravitational distortion model, and the geometrical distortion model.
