Module length considerations 15/02/17

Short - Long Component Active Girder Mule Passive (0. 5 mm) Floor Active Plate Floor Passive (10 um) Passive (0. 5 mm)

Actuators • Screw based • ~10 mm of range minimum • low load (30 -300 N) • No constant power • Piezo • ~0. 1 mm range • Relatively high load • Constant power • Cam movers • Not enough data • Screw based + leverage seems the best • No info for radiation hardness

Linear Actuators • Difficult to estimate price • Need more data points • Very difficult to find off the shelf ‘big’ actuators name load cost standa 8 CMA 42 300 N 2900 standa 8 CMA 06 30 N 1500 PI L-239. 50 300 N 2500 M-229. 26 S 50 N 550 PI custom 4000 N 10000 Cost (k CHF) • Gear reduction necessary 10 9 8 7 6 5 4 3 2 1 0 R 2 = 0, 9687 0 500 1000 1500 2000 2500 Load (N) 3000 3500 4000

Scenarios (SAS) • 50 kg/SAS • 100 kg/m for girder material • Excluding controller costs • Excluding passive elements alignment effort • Excluding WPS sensors • 2 Do.
