Measurement Report: Elastic Base
Feet for Electrical Appliances
Successful isolation of unwanted noise andtroublesome vibrations
Description of the project
High-quality, high-performance blenders are essential
for the preparation of sparkling cocktails, mixed beverages and smoothies. However, unwanted vibration of thedevice is also associated with the high performance andspeeds, which can spread from the base feet to the entire
counter or worksurface. These vibrations are then accompanied by disruptive noises.

Blender causes
vibrations

Getzner Werkstoffe has developed a solution for thisproblem: elastic base feet made from Sylodyn®, which
protect the worksurface from vibrations and impacts. The
two-part combination of the innovative Getzner base feet
ensures both efficient vibration isolation and stability ofthe device. The original, hard base feet on the blenderwere easily replaced with new Getzner base feet.

Advantages:— High cost-benefit effect— Maintenance-free— Consistent material properties— Reduction of vibrations

Comparative measurement process
In order to verify the effectiveness of the Getzner base feet, the following measurement was taken with both theoriginal feet and the new Getzner base feet. Once the blender attachment had been filled with fruit and vegetablepieces, the measurement process was started and the blender was then operated at a constant rotational speed.
After roughly 20 seconds, the ingredients had been blended into a fine pulp and the measurement was completed.
Measurements were taken at four different measurement points (MP) in total (see experimental set-up), and theacceleration was measured at each point.

MP4: glass shelf

MP1: on the device

MP2: near the device

MP3: at a distance from the device

Measurement results for vibration reduction
Two operating states were examined during the respective measurements:— Phase 1: Immediately after starting the blender – when
the fruit and vegetable pieces are being chopped intosmaller pieces (approx. 5 seconds). Comparatively highaccelerations occur, which is why the maximum acceleration was considered in the results.

— Phase 2: Once the ingredients had been blended intoa pulp, the acceleration was reduced and remained ata more or less constant level. The average acceleration
was used for the results.
On average, the Getzner Sylodyn® base feet reduced
acceleration and thus vibrations by 70 % in phase 1 and
57 % in phase 2.
