Type-A Meeting on 2016/6/14
2016/6/14 13:00 - 15:00 @ Room 210
Participants: Takahashi, Ishizaki, Sato, Okutomi
Minutes
- 0-1 Assembly model (Ishizaki)
- Step: From EQ stop, next with chamber.
- Problem: Conversion to Simulink was ok. The structure of control has a problem in Matlab. Reconstructing now.
- Space: Make working space in the 20m lab.
- Design: 5 blades are used for 200kg load.
- Device: Asking design of LVDT-Act. to VIRGO. The device is located at the center of mass.
- Structure analysis: Two cases were calculated. Share stress was 1/6 of limit, and principal stress was 1/7 of limit respectively in the maximum case.
- Modeling: Making with consideration of procedure and tools.
- Frame lock: Maximum stress was 160MPa with thickness of 30mm (limit 180MPa).
- Position: Inner side of the stage. Need to addtional machining to the EQ stop plate.
- Electronics: Circuit is simple in the test (handmade).
- Condition: 25cm mirror, alignment by moving mass. Make a cartoon.
- Actuation: Length control is necessary? Check PZT actuator.
- Test plan: Prepare for 2 sets of release sensors. Check FR for 2 BFs.
