Static and Dynamic Analyses on the MFTF-B Vacuum Vessel. Revision 1

摘要

The Mirror Fusion Test Facility is a major magnetic fusion energy project at the Lawrence Livermore National Laboratory. An important component of this facility is the vacuum vessel, which forms the vacuum chamber. The vessel is supported on twenty-two pairs of legs that rest on reinforced concrete piers. In performing static and dynamic analyses on the vacuum vessel, we separately investigated the load distribution under gravity loads, pressure loads, electromagnetic loads, and thermal loads. We also performed sophisticated dynamic analyses to predict the structural behavior under a postulated earthquake. The modeling assumptions and analytic procedures are highlighted in this paper.
