20.3. Use with passive vibration insulation (tuned to a low
frequency)
Selection criteria: Mobile use
The system can be tuned to a low frequency by installing a flexible
bearing.
For example, you can attach the mounting bracket to elastomer springs or rubber buffers.
The ideal total spring constant should be dimensioned in such a way so that the natural
frequency of the system falls below the lowest excitation frequency.
All excitations with a frequency greater than 1.4 times the natural frequency would then
be dampened by a counter-phase effect. This is practically impossible, if you consider
that excitation accelerations within the range of around 10 Hz to 200 Hz or more may
occur. Furthermore, the springs of the DLoG MPC 6 would strongly deflect while static or
visibly swivel while resonating (blurred display).
Based on our experience, we have found that the natural frequencies of unsprung
ground vehicles lie between 15 Hz and 25 Hz. Although the elastic bearing does create
an interfering resonance, it can suppress high excitation frequencies to various degrees
of success.
