Minutes of the VIS Meeting on 2016/6/17
2016/6/17 13:30 - 15:00 @ Room 210
Participants:
Progress report
Type-A (Takahashi)
- Put a report here
Type-B (Mark)
- Put a report here
Type-Bp (Shoda)
Create a rough new LVDT model -> Saito-san found that they fit around the BF.
Assembly plan for Modified Type-Bp: JGWdoc -> asked Saito-san to do more upgrade.
- Upgrade points: some screw sizes were wrong. Move the security poles inside so that we can fix them from the top.etc...
- I found that we cannot load on the BF than I expected before.
- The model of the BF was updated recently. When we decided the plan BF, the model was wrong, which means that the mass was wrong.
- The load on the SF GAS = Tha mass on the BF GAS: 53.5 kg + IRM: 9.0 kg + BF: 100.2 kg = 162.7 kg
- The optimal load on the SF GAS is 164.3 kg (minimum for the SFs whose caps cannot be closed).
- The weight of the actuator base is currently 1.9 kg (w/o coils and magnets).
- I suggest to gain weight margin by reducing the moving masses on the cap.
