Study on the Thermal Stress Couple Field of Nuclear Power Pump Mechanical Seal Based on ADINA

In this paper, a two-dimensional axisymmetric thermal stress coupling model of mechanical seal’s rotator and stator components was established by ADINA, simplification and appropriate boundary constrained condition of stator and rotator was obtained by analyzing the contact state among the seal rings. It’s shown that the contact surface is equivalent to a resource of constant thermal, temperature…
