SUMMARY

When selecting anti-vibration mounts, it is essential to focus on the damping mechanism to match the natural frequency of the system without the damper. Key factors include analyzing the damping constant plot to determine the damping constant (c) and estimating a suitable spring constant. For systems with multiple degrees of freedom, advanced equations can be utilized to derive the c value effectively. These steps ensure optimal vibration isolation and system performance.

PREREQUISITES
  • Understanding of damping mechanisms in mechanical systems
  • Familiarity with natural frequency concepts
  • Knowledge of spring constants and their calculations
  • Experience with multi-degree-of-freedom systems
NEXT STEPS
  • Research methods for analyzing damping constant plots
  • Learn about calculating natural frequencies in mechanical systems
  • Explore advanced equations for multi-degree-of-freedom systems
  • Investigate different types of anti-vibration mounts and their applications
USEFUL FOR

Mechanical engineers, vibration analysts, and anyone involved in selecting or designing anti-vibration systems will benefit from this discussion.

Could someone tell me what are the factors needed to be looked into before selecting Anti-vibration mounts.

Regards.

Basically you want the damping mechanism to achieve the same natural frequency and the system without the damper. So you need to examine the damping constant plot and look at its envelope. From this you will find your c, or damping constant. Then from this you can guess a reasonable spring constant and start figuring it out. If you have experience with system more than one degree of freedom the c value can be found with those equations as well
