  1. UMBRELLA STRUCTURE UPGRADATION Srinivas Avasarala Mechanical Engineer III Princeton Plasma Physics Laboratory Princeton, NJ

  2. SOLID MODEL CONSTRUCTION THE NEW MODEL HAS 10 SCALLOPS 8 7 9 6 10 5 1 2 4 3

  3. LOADING INPLANE LOADS TORSIONAL LOADS 21314 N 22341 N 25628 N Fixed all 10 legs

  4. RESULTS STRESSES FOR BOTH INPLANE AND OUT OF PLANE LOADS STRESSES FOR OUTPLANE LOADS STRESSES FOR INPLANE LOADS Max Stress = 650 Mpa Max Stress =350 Mpa

  5. SUPPORTING THE SCALLOPS

  6. STRESSES WITH THE SCALLOPS SUPPORTED Stresses dropped from 350 to 110 Mpa

  7. CENTER HOLES SUPPORTED

  8. Final FE Model The Aluminum center block has been added to model in place of the supports we have seen in the previous slides Circular contact regions are defined to simulate bolt pattern. The legs are mounted on a circular metal plate to give it some compliance. The scallop supports are altered a little.

  9. Final Results (In-plane Loads)

  10. Final Results (Out-plane Loads)

  11. Final Results (Both-plane Loads)
