May 18, 2020 – Cleveland, Ohio, USA – MB Dynamics, Inc. (www.mbdynamics.com) (MB), field-proven industry experts of nearly 40 years in the design, manufacture and supply of vibration test systems and equipment, including buzz, squeak and rattle (BSR) test systems, steering test systems, and suspension component test systems; modal exciters and amplifiers; single- and multi-DUT automated accelerometer calibration systems; dynamic controllers; transducer calibration systems; and test engineering services, today announced the 600th successful field installation of its Energizer™ Series, a family of extremely quiet vibration exciters for buzz, squeak and rattle (BSR) testing.
Offered in four unique sizes and models, and under the trade names of Energizer BLACK, BLUE, RED, and SILVER, respectively, each vibration exciter offers its own unique peak force and maximum payload specifications. The exceptionally low operating background noise of the MB Energizer Series actually fulfills Noise Rating Curve 18 requirements. When running a typical S&R random vibration profile, Energizer Series noise levels are consistently below 28 dB(A) and at less than 1 Sone N10 Stationary Zwicker Loudness. These features allow an end-user to effectively support a variety of demanding BSR testing and evaluation requirements while reducing risks of measurement uncertainty caused by the presence of unwanted vibration exciter noise within the BSR test environment.
Among Series models, the Energizer SILVER vibration exciter, in particular, has been formally designated for the support of automotive industry subjective and objective BSR evaluations as set forth within GMW14011, GM7293TP, BMW PR311-2 and PSA, “specification bruit parasites”, as well as within several Hyundai engineering standards, making the Energizer Series truly industry best-in-class among its peers for any such requirements.
The robust design of each MB Energizer Series vibration exciter incorporates a proprietary, permanent magnetic-based technology. That technology is combined with the patented, quiet and stiff frictionless suspension of the Energizer Series’ moving element, thereby eliminating the need for noisy cooling fans and blowers. Each Energizer Series vibration exciter system further includes 2:1 and 3:1 force-multiplying lever arms, thereby increasing exciter force output by 2X or 3X, respectively, along with air spring load support of up to 90 kg for vertical testing.
For non-BSR work, as such BSR aging and durability testing, the Energizer Series further offers forced air cooling. This feature helps an end-user to double uncooled vibration exciter force outputs. Thermal shutdown protection is also included to prevent the vibration exciter from overheating. Also offered is a chamber readiness kit, for proper use of the Energizer Series within environmental test chambers operating from -40°C to +65°C, including humidity.
The MB Energizer Series features trunnion bases for either vertical or horizontal operation. The vibration exciters are also available with end-user choices of multiple mounting table sizes. Each table is large enough for test items, yet small enough to minimize speaker effects which can otherwise radiate unwanted noise. Horizontal Moving Tables (HMT) are available for quiet horizontal testing using the same patented quiet flexures. They further incorporate quiet, no oil-film slip tables and guidance bearings for additional payload support during X- and Y-axis testing. A series of air casters and air lifter accessories are also available for moving the Energizer Series vibration exciter over smooth floors or the tops of a T-slot base plate. Other accessories and customization may be available, as well as test engineering service support. Please consult the team at MB Dynamics for application assistance.
