Monthly Report for Space Robotic FMS PreCommercialization Development April 30, 2019
Continued testing with nominal strut tension. Modified method of viewing data has increased number of trackable modes below 3300 Hz.
Software Simulationno change
Breadboard Manufacturingno change
Have identified phase shift excitation that excites almost all modes below 3300 Hz. Two modes seem to have split and it may be the tensioning on shear modes that causes it.
- axial (all 4 segments in phase)
- rocking (4 sets)
- 1/2 saddle (2 sets)
- individual segments (4: 0,1,2,3)
Plans for May.
complete testing of nominal strut tension condition and modify it slightly to consider influence.
