=== Minutes === 0-1 Assembly model (Ishizaki): From EQ stop, next with chamber. 0-2 Simulation (Okutomi): Conversion from SUMCON to Simulink was ok. Problem is the structure of control in Matlab. Reconstrunting now. 3-5 ACC preparation (Sato): Make working space in the 20m lab. 5-1 Manufacturing of blade (Takahashi): Target of 200kg, 5 blades are used. 5-6 Design of damper (Sato): Asking design of LVDT-Act. from VIRGO. The device is placed 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 in the max. case. * Modeling: Making with consideration of procedure and tools. * Frame lock: Max. stress was 160MPa with +5mm thickness (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 Test plan: Prepare for 2 sets of release sensors. Check FR for 2 BFs. |
