LIGO-G M Advanced LIGO1 Finite Element Modeling Requirements Dennis Coyne Advanced LIGO, Seismic Isolation System (SEI) Structural Design & Fabrication Bidder’s Conference April 29, 2003

LIGO-G M Advanced LIGO2 FEA Requirements Scope & Definitions Contractor must perform finite element analyses to verify compliance with the stiffness requirements (sections C.7 HAM; C.9, BSC) »Earthquake/strength analyses are optional via FEA (not required) »Must include representation of all elements of the structures including: –External support including support tubes, mounting caps and bases, crossbeams, crossbeam attachment plates, crossbeam feet (pointed at 45 deg, toward the chamber center) –Instrumentation pods –Payload (non-suspended) »Models must be delivered to LIGO »Contractor plan for FEA to be reviewed at Kick-off meeting »FEA results must be reviewed and approved by LIGO before committing to fabrication »Must beat requirements in finite element modeling by 10% in frequency (see SOW) BSC Support Structure HAM Support Structure

LIGO-G M Advanced LIGO3 FEA Requirements Stiffness/Frequency Requirements For common-corner seismometer/actuator and displacement sensor/actuator pairs that share an axis direction on stages 1 and 2: the phase of the transfer function Xsensor/Xactuator shall be greater than -90 degrees for all frequencies below 500 Hz For all other pairs of seismometer and actuator, and displacement sensor and actuator on stages 1 and 2: the phase of Xsensor/Xactuator shall be greater than -90 degrees for all frequencies below 150 Hz For all pairs of displacement sensor and actuator on stage 0: the phase of Xsensor/Xactuator shall be greater than -90 degrees for all frequencies below 100 Hz »Exception for effect of external structure modes

LIGO-G M Advanced LIGO4 FEA Requirements Example Calculation Example Structure »Approximate size of the stage 1 BSC system »Has 3 “corners” where actuation and sensing is placed »Includes three beam structures, mid-span along the sides of the stage 1 ring – creates local modes which do not couple well to the global structure modes Frequency Response Analysis »Modal analysis performed with Algor and I-DEAS »Displacement Transfer Functions calculated with I-DEAS Co-located Actuator and Sensor Non co-located Sensor
