چکیده
A Multi-body contacting Thermal-Elastic-Hydro Model, MTEHM has been established in this study. And which applied to analysis the leakage behavior of No.1 seal RCP hydrostatic seal. The hydro-model is based on 2D Reynolds equation and programmed by M-code. An interface program written C carried out. used transit end face pressure value from elastic-solid model. FEA multi-body method taken into obtain deformation angle rings. opening force ratio out as a convergent judgment multi-physics iterative coupling process. influence position O-rings (on back rings relative clamp rings) discussed. For test verify MTEHM, testing rig established. It can be simulate high temperature media with range 22°C 100°C 0.1MPa 22MPa. At last, comparison pressure-leakage data Westinghouse, Saint Alban power plant study presented. variance attached.
