Compact Shake & Rattle Systems
Ideal For Squeak & Rattle Tests And Fatigue Strength Tests
The lightweight & compact ALPHA electrodynamic shakers from MB Dynamics impress with their high efficiency and very low operating noise. The robust, low-maintenance design and excitation forces of up to 4000N allow universal use of the ALPHA shakers for squeak & rattle tests and fatigue strength tests on various components in 1 to 6 axes.
Integrated temperature-controlled silent fans, active pneumatic load support and extensive safety and monitoring functions ensure reliable and safe continuous operation even with higher excitation forces. All ALPHA vibration shakers meet the strict requirements of GMW 14011, BMW PR311 and TPJLR.00.187 as well as other Squeak & Rattle test specifications regarding the maximum permissible operating noise of the shaker used. The monitoring of the shakers and the control of the associated power amplifiers is carried out from the central test bench computer via a control app that is included.
Key features of the Alpha Shakers include friction-free guidance of the moving element for precise testing, integrated laser displacement sensors for accurate monitoring, and automatic load compensation for seamless adjustments. The quiet, temperature-controlled fans ensure optimal conditions without the noise of traditional fans. The robust design requires minimal maintenance, ensuring long-term reliability.
Optional noiseless water cooling allows for quiet continuous operation even under high excitation forces. With thermal insulation and a combined heating/cooling aggregate, the ALPHA systems can operate in climatic chambers within a temperature range of -40°C to +80°C, providing exceptional versatility.
