SELF-SANITIZATION AGAINST BACTERIA AND FUNGI
Guidelines for the choice
Guidelines for the choice
Analysis of the static tests to select the appropriate vibration damper.
Basic data required:
- The static load applied to each vibration damping element (acting on each support point).
- Disturbing frequency to be reduced and the desired isolation percentage.
How to choose the vibration-damping element:
- With reference to the diagram for the check of the isolation degree, locate the corresponding static deflection required to obtain the desired isolation.
- Select the product with the required static deflection depending on acting load.
Example:
Consider an application with the following features:
- Static load on each support: 1400 N
- Frequency to be isolated: 1.200 rpm = 20 Hz
- Required isolation: 90% at 20 Hz
For vibration dampers without damping e.g. AVM, the following diagram for checking the isolation degree shows that a static deflection of at least 7 mm is required to obtain 90% isolation of the 20 Hz frequency, In case of damping, the isolation percentage may vary, it is advisable to contact the Elesa Technical Department.
With reference to the graph below the products that intersect the 1400 N line are: AVF, AVG, AVM.
For the 1400 N load, the expected static deflections are:
- AVF: approximately 4 mm (< 7 mm) = approximately 80% isolation at 20 Hz
- AVG: 6.5 mm (< 7 mm) = approximately 88% isolation at 20 Hz
- AVM: 13 mm (> 7 mm) = approximately 95% isolation at 20 Hz
Consequently, the most suitable product with the best isolation degree is AVM.
