Spectral Dynamics, Inc. Air Cooled Low Force Shaker SD-440-6/DA-2

SD-440-6/DA-2 Low Force Shaker Series Features Air Cooled 440 lbs (200 kgf) Sine Force 440 lbs (200 kgf) Random Force 38 mm Peak to Peak displacement Large diameter, lightweight armature Double Field Coils (Upper and Lower) design Ultra-Compact energy efficient amplifier Available combined with slip table Sine, Random and Transient Testing Standard cooling blower silencer Standard Vertical and Horizontal Operation Typical System Application The Model SD-440-6 Series Vibration test system is a versatile wide frequency range electrodynamic vibration test system. It is designed to test payloads weighing around 200 lbs such as electronic assemblies and components for larger devices as may be found in automotive, aviation, military, medical, and electronic manufacturing industries and Civil Engineering applications. The system consists of a model SD-440-6 shaker and is driven by the Model DA-2 power amplifier and a 0.75 KW cooling blower. The model is capable of a Random RMS force of 200 kgf and Sine Vector force rating of 200 kgf in the frequency of DC to 4,000 Hz under controlled conditions. Standard vibration systems consist of an electro-dynamic exciter (the "shaker"), a state-of-the-art air-cooled switching power amplifier with field power supply and a water cooling unit. Optional items including slip tables, head expanders, accelerometers and vibration controller can be added upon request. How to select the suitable model It is critical to consider the size and position of the test article and the total moving mass of the payload as well as the payload's inertial and overturning moments when selecting a system for your application. It is recommended the force selected should be 1.2 times the theoretical value, to insure appropriate safety margins. For assistance selecting the best system for your needs, please contact our sales representative. High FRF & Wide UF Our new shaker design significantly raises the FRF (Fundamental Resonance Frequency) and UF (Useable Frequency) of our long stroke systems and outperforms similar products from other manufacturers. Reliable Armature The unique reinforced armature structure design is state-of-the-art, providing increased reliability and unsurpassed performance. Our proprietary armature structure has been re-designed to optimize its rigidity and force transmissibility. Designed for continuous duty and ideal for research & development, production, stress screening and qualification testing, our ruggedized armatures can endure severe vibration and shock forces and extreme temperature conditions. Efficient Air Cooling The shaker and power amplifier are totally air cooled for easy installation and economical operation. Cooling Blower Unit The suitable Cooling blower is ACU751 as specified below. Air-Isolated Rotating Trunnion All shakers come standard in a rotating trunnion for easy 90° rotation between the horizontal and vertical test axes. A labor-saving worm wheel is designed for this rotation, which make it friendly for both men and women. Trunnion are pneumatically isolated (except low force series) providing high stability and allowing for direct mounting onto conventional industrial concrete floors. All shakers are optionally available with an integrated or stand-alone slip table assembly. D-Class Switching Amplifier Our state-of-art modular switching amplifiers are 100% air-cooled with redundant safety systems and system interlocks insuring performance that is reliable and stable. All amplifiers adopt IGBT power modules of high quality. Safety Products comply with European tests standards and ISO regulations.
