Thermally Conductive Vibration Isolation System for Cryocoolers |
 AFRL Phase II SBIR
|
Active vibration control in pulsed resonant cryocoolers
Vibration compensation using compact six-axis electromagnetic actuators
- 100:1 reduction in cryocooler drive axis
- 20:1 reduction in cross-axis
Heat transfer from cryocooler displacer using flexible carbon fiber strap is ten times more efficient than copper
Six axis actuator system successfully tested at NIST with axial/radial reductions of:
- Drive frequency > -40 dB (>100:1)
- First four harmonics > -20 dB
System developed jointly by CSA Engineering and TAI
|
|
|
|
| Single axis derivative provides simple control solution :
|
Compact & inexpensive system!
Axial reduction of:
- Drive Frequency > -42 dB
- First four harmonics -20 to -40 dB
- Fifth through tenth harmonic -16 dB avg.
