  1. Telescope Vibration Isolation Hannah Dembowski Brian Ferraro Domenic Salvatore

  2. The Problem • Vibrating at 150 microns (9 microns/pixel) • Need to reduce to between 9 and 15 microns

  3. 68-500 SERIESHigh-Capacity Lab Table • high load applications (over 350 lbs) • unusually high centers of gravity and equipment with moving stages

  4. Vibration Isolation for Telescope Mounts • mobile observatory applications • walking around telescope tripod or pier induces vibrations • Reduce vibrations if pier or tripod is bumped

  5. 65 SERIES Floor Platform with STACIS® • piezoelectric isolators • platform custom designed for footprint

  6. Telescope

  8. Telescope Mount Design Options Design 1

  9. Telescope Mount Design Options Design 2

  10. Telescope Mount Design Options Design 3

  11. Modeling

  12. Governing Equations

  13. Design Comparison

  14. Design Comparison: Design 1

  15. Design Comparison: Design 2

  16. Design Comparison: Design 3

  17. Final Design

  18. Feasibility • Modeled 4th floor I-beam layout • Ensure the extra load will not exceed maximum allowable

  19. Construction • Rowan Facilities Department • Able to complete construction, after graduation ceremony

  20. Cost analysis • Facilities has concrete and cinderblocks • Leaves cost of air springs • Roughly $200-$300

  21. Future Steps • Implement the system designed in option 3 • Test solution • Measure final vibrations • New photos
