  1. SPOKE TUNER STATUS M. Merio, D. Passarelli , L. Ristori

  2. MODEL AND ASSUMPTIONS S L STEPPER MOTOR Stretchadjustment S/3 Motor arm MAINARM PROBES Squeeze adjustment Drive nut PIEZOS L/2 Tuner with symmetry boundary conditions imposed • Assumptions: • The Tuner is symmetric, only half model will be considered • Material: SS316 L • RT analysis FULCRUM

  3. TUNER MAIN ARM Loads and Boundary Conditions: Stiffness

  4. MOTOR ARM – Load @ PIEZO Loads and Boundary Conditions: Stiffness

  5. MOTOR ARM – Load @ MOTOR Loads and Boundary Conditions: Stiffness

  6. MOTOR SUPPORT Loads and Boundary Conditions: Stiffness

  7. PLATE Loads and Boundary Conditions: Total Force acting on the bolts:

  8. CONCLUSIONS • A first coarse analysis has been done to evaluate the behavior of the main components of the tuner • Stiffness and Stresses have been investigated • Future work: • Verify if the requirements listed before have been satisfied • Thermal analysis • Analysis of the entire assembly • Failure analysis THANKS FOR THE ATTENTION
