Understanding the Key Factors in Anti-Vibration Rubber Mount Selection

Load Capacity and Deflection

When choosing an Anti-Vibration Rubber Mount, one of the primary considerations is its load capacity and deflection characteristics. The load capacity refers to the maximum weight the mount can support without compromising its performance or structural integrity. It's crucial to select a mount that can adequately handle the static and dynamic loads of your equipment. Overloading a mount can lead to premature failure and reduced effectiveness in vibration isolation.

Deflection, on the other hand, is the amount of compression or displacement the mount undergoes when subjected to a load. The relationship between load and deflection is typically non-linear for rubber mounts, which means that as the load increases, the deflection doesn't increase proportionally. This non-linear behavior contributes to the mount's ability to isolate vibrations across a range of frequencies.

To determine the appropriate load capacity and deflection for your application, consider the following:

• Total weight of the equipment to be isolated
• Distribution of weight across multiple mounts
• Dynamic forces generated during operation
• Desired natural frequency of the isolated system

Frequency Range and Isolation Efficiency

The frequency range of vibrations your equipment generates or experiences is another critical factor in selecting the right Anti-Vibration Rubber Mount. Different mounts are designed to provide optimal isolation within specific frequency ranges. To effectively reduce vibrations, the mount's natural frequency should be lower than the lowest frequency of vibration you're trying to isolate.

Isolation efficiency is typically expressed as a percentage and indicates how much of the vibration energy is prevented from being transmitted through the mount. Higher isolation efficiency means better vibration reduction. However, it's important to note that no mount can provide 100% isolation across all frequencies.

To select a mount with the appropriate frequency range and isolation efficiency:

• Identify the frequency range of vibrations in your application
• Consider any potential changes in operating conditions that might affect vibration frequencies
• Look for mounts with a natural frequency that's about 1/3 to 1/2 of the lowest disturbing frequency
• Evaluate the isolation efficiency curves provided by manufacturers
