Spectral Dynamics, Inc. Water Cooled Shaker SD-22200-25/DA-120

SD-22200-25/DA-120 Water Cooled Shaker Series FEATURES Water Cooled 24,200 lbf (12,000 kgf) Sine Force 22,200 lbf (12,000 kgf) Random Force 2 Inches (51 mm) Peak to Peak displacement Large diameter, lightweight armature Double Field Coils (Upper and Lower) design Ultra-Compact energy efficiency amplifier Available combined with slip table Sine, Random, and Transient Testing Standard Vertical and Horizontal Operation Typical System Application Model SD-22200-25 Series Vibration test system is a versatile wide frequency band electrodynamic vibration test system. It is designed to test small to large sized payloads such as spacecraft components, large mechanical structures, automotive systems that require high force, most military products, etc. The system consists of a model SD-22200-25 shaker and is driven by the model DA-120 power amplifier and the model CU-120 water cooling unit. Wide Useable Frequency Band The high performance shaker powered by an efficient DA-120 switching power amplifier operates over a useful frequency range from 5 to 2,300 Hz. The amplifier is designed using the latest IGBT module Technology. High Fundamental Resonant Frequency A unique light weight stiff aluminum alloy is employed for the armature to increase the first resonance to 1,900 Hz. A STIFF armature increases the probability that your test loads will not reduce the first resonant frequency. An optional magnesium armature is also available for alternative applications. High Overturning Moment Armature design incorporates four robust roller-structures for top guidance and a unique roller-bearing for bottom guidance. The distance between the top and bottom guidance systems is longer than many systems, enhancing stability. This approach helps reduce the overturning moment for heavy test articles which may have a high center of gravity. Water Cooling Unit: CU-120 The water-cooled shaker series incorporates the industry’s most advanced and efficient coil cooling technique, called “Parallel-Concurrent ” Coil Cooling. The parallel cooling technique surpasses other manufacturers’ series cooling designs in thermal transfer efficiency during full load operation. Automatic Internal Pneumatics For High Payload A superior pneumatic load support system guarantees a full nominal displacement with a maximum vertical load up to 5511 lbs (2,500 kg) for test specimen and fixture. An auto-centering pneumatic load support system is available as an option to enhance the performance of the system. Standard Vertical and Horizontal Operation The SD-22200-25 shaker comes standard with VH configuration. The shaker can be operated in either a vertical or a horizontal direction and can be used in combination with an integrated or stand-alone slip table or environmental chamber with optional thermal barrier. An optional worm wheel system may be added to the trunnion making it easier to change the thrust direction. Safety The emergency stop switches on the shaker body and amplifier are installed. All the inner terminals are people safe. An armature temperature monitor is included. These features and more make the SD-22200-25 a reliable and affordable system for your applications.
