Typical System Application |
|
 |
The Dongling family of Air-Cooled Vibration Test Systems are well suited to test a wide range of products. Requiring no cooling water, air cooled shakers are easy to install and are widely used for commercial and military applications in the fields of aerospace, aviation, defense, watercraft, telecom, automotive, electronics, home appliances and more. With output force ratings from 100 kg to 7,000 kg peak force, these shakers are designed to provide continuous duty over a wide-band frequency range of up to 3000 Hz.Additional standard features include: integral payload support, rotating trunnion base with pneumatic isolation, 1:1 Sine to Random output force ratio and high fundamental armature resonance.All Dongling Vibration Systems are built and tested in full compliance with ISO-5344.
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 remote cooling blower. Optional items including slip tables, head expanders, accelerometers and PUMA or JAGUAR vibration controllers 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. Dongling recommends 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 a Dongling sales representative.
High FRF & Wide UF
Our new shaker design significantly raises the FRF (Fundamental Resonance Frequency) and UF (Useable Frequency) of our air-cooled systems and outperforms similar products from other manufacturers.
Reliable Armature
Dongling’s unique reinforced armature “ring” design is state-of-the-art, providing increased reliability and unsurpassed performance.Our proprietary armature ring 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
Recently re-engineered for optimal cooling capacity, the efficient airflow design contributes to our system’s outstanding overall reliability.Our new and improved airflow cooling design uses more efficient long air tunnels instead of circular inlet paths and a new state-of-the-art honeycomb design for maximum field coil cooling capability.
Cooling Blower with Silencer
Remote cooling blowers equipped with noise-reducing silencers are appropriately sized to provide optimum cooling efficiency and are included with all air-cooled systems.
Air-Isolated Rotating Trunion
All Dongling shakers come standard in a rotating trunnion for easy 90° rotation between the horizontal and vertical test axes. Dongling trunnions are pneumatically isolated 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.
Safety
Products comply with European tests standards and ISO regulations.
