=== Minutes === 0-1 Assembly model (Ishizaki) * Step: From EQ stop, next with chamber. 0-2 Simulation (Okutomi) * Problem: Conversion to Simulink was ok. The structure of control has a problem in Matlab. Reconstructing now. 3-5 ACC preparation (Sato) * Space: Make working space in the 20m lab. 5-1 Manufacturing of blade (Takahashi) * Design: 5 blades are used for 200kg load. 5-6 Design of damper (Sato) * Device: Asking design of LVDT-Act. to VIRGO. The device is located at the center of mass. 6-1 Design of EQ stop (Ishizaki) * 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). 6-4 Design of release sensor (Sato) * Position: Inner side of the stage. Need to addtional machining to the EQ stop plate. * Electronics: Circuit is simple in the test (handmade). 8-1 Design of dummy payload (Okutomi, Ishizaki) * Condition: 25cm mirror, alignment by moving mass. Make a cartoon. * Actuation: Length control is necessary? Check PZT actuator. 9-1 Establishment of procedure (Takahashi, Okutomi) * Test plan: Prepare for 2 sets of release sensors. Check FR for 2 BFs. |
