OVERVIEW
- E-STA structural vibration testing performed on mechanical vibration facility (MVF) at NASA Plum Brook Station in Sandusky, Ohio
- Large nonlinear behaviors observed in test article during vibration testing
- Preliminary model correlation shows high sensitivity to the Pyramidal Separation Mechanism (PSM) joints
- Initial comparison of load share within primary structure indicates FEM distributes too much load to the inner load path during full level testing
