Design Equations for Initially Flat Blade Springs at Arbitrary Mounting Angles

Document #:
Document type:
T - Technical notes
Other Versions:
Design equations are developed for initially flat blade springs mounted at arbitrary tilt angles. Blade Spring Tests were performed for several configurations. The test mass required to deflect the blade to the design height agreed with the design value 10%. The radius of curvature of the loaded blade spring agreed with the design value 1%.The predicted vertical bounce frequency under load agreed with the measured value to 1 %.
Notes and Changes:
added experimental data from Faraday Isolator prototype with C-250 maraging steel springs
