When a system's natural frequency and the expected forced vibration frequencies line up, this is known as resonance, and it results in high amounts of vibration.
Stiffness and bulk have an impact on the system's inherent frequency.
This relationship is shown as an equation with the following values: , where m is the mass and k is the stiffness.
We must modify either k or m, or both to adjust the natural frequency.
The goal is to raise the natural frequency so that it is higher than any significant vibration frequencies that are anticipated.
To reduce a system's vibration response by altering its natural frequency, keep the following guidelines in mind:
The natural frequency is raised by adding stiffness.
When the mass is added, the natural frequency decreases.
