EDDY CURRENT-BASED VIBRATION DAMPING FOR AEROSPACE STRUCTURES

SATCON HAS DEVELOPED AN EDDY CURRENT-BASED VIBRATION DAMPER READY TO ADVANCE DISC DRIVES, HOME AUDIO AND VIDEO EQUIPMENT, VIBRATION ISOLATION SYSTEMS FOR INDUSTRY AND INSTRUMENTATION, AND EVEN AUTOMOBILE SUSPENSIONS. THESE DAMPERS ARE REMARKABLE FOR THEIR LINEARITY, RELIABILITY, WIDE RANGE OF OPERATING TEMPERATURES,AND THEIR SPACE ENVIRONMENT COMPATIBILITY. SATCON HAS ESTABLISHED DESIGN GUIDELINES WHICH ENSURE DAMPERS WITH LINEARITY AND MAXIMUM VIBRATIONAL ENERGY PER UNIT DAMPER MASS. THE RESULT IS A SET OF PRACTICAL DAMPER DESIGNS WHICH CAN PREVENT VIBRA-ACOUSTIC FATIGUE IN AIRCRAFT, SUPPRESS VIBRATION IN A SPACE TRUSS STRUCTURE, OR PROVIDE DAMPING FOR VIBRATION ISOLATION. THE NONCONTRACTING NATURE, THE ABSENCE OF WEAR AND SUCTION, AND THE EXCEPTIONAL LOW TEMPERATURE PERFORMANCE SUGGEST THEIR USE IN A WIDE RANGE OF CRITICAL AND DEMANDING APPLICATIONS FROM CRYOGENIC TO NOISE QUIETING TO PRECISION POINTING AND POSITIONING.
