Mechanical vibration isolators

A Simple Introduction to Vibration Isolation

Today’s industrialized world is full of mechanical vibrations and these vibrations are all around us. Transportation, energy, technology, entertainment, communication, healthcare, finance and so much more would jackhammer through our lives each day if not for a simple solution called a vibration isolator.

Simply put, vibration isolators are commonly used in applications where mechanical vibrations occur to dampen those vibrations. Vibration isolators are most often made from bonding various metals and rubber compounds together in a process called vulcanization. The variability of metals and rubber compounds offers flexibility to isolate vibrations properly and withstand the unique environmental conditions each isolator will be subjected to in its application.

Enterprise Rubber, Inc. has specialized in manufacturing vibration isolation mounts for nearly 50 years. Our off-the-shelf parts are manufactured in common sizes and configurations but can also be customized based on the unique requirements of our customers. We manufacture in a variety of compounds, durometers, and mount configurations. Read on for a brief explanation of our most common mount types.   

*PLEASE NOTE – Vibration isolation mounts are designed to be used in compression and shear applications and are not recommended when pull-force or torque-force is required. It is your responsibility to determine whether our off-the-shelf parts will work in your application, even when customization or manufacture-to-order occurs.  

What Is The Purpose of Vibration Isolation

The purpose of vibration isolation is to reduce or eliminate the transmission of vibrations and shocks from one source to another, typically in mechanical systems or equipment. Vibration isolation serves several essential functions:

Protection: It protects sensitive components, machinery, and equipment from damage caused by excessive vibrations and shocks, extending their lifespan and reliability.

Improved Performance: By isolating vibrations, mechanical systems and equipment can operate more smoothly and accurately, leading to better overall performance.

Comfort: In applications like automotive and construction, vibration isolation enhances the comfort and safety of passengers and operators by reducing the impact of road vibrations or machinery vibrations.

Noise Reduction: Vibration isolation minimizes the transfer of noise associated with vibrations, leading to quieter and more pleasant environments.

Safety: It enhances safety by reducing the risk of structural damage and mechanical failures caused by vibrations and shocks.

Vibration isolation is critical in various industries, including manufacturing, construction, automotive, and aerospace, to ensure the longevity, reliability, and comfort of both equipment and personnel.

What Is an Example of Vibration Isolation

An example of vibration isolation is the use of anti-vibration mounts or isolators in a washing machine. These rubber or elastomeric mounts are placed between the appliance's motor and the machine's frame. When the washing machine is in operation, the motor generates vibrations. The anti-vibration mounts effectively absorb and dampen these vibrations, preventing them from transmitting to the machine's exterior or the floor. This not only reduces noise but also protects the surrounding area from the potentially damaging effects of the machine's vibrations, such as structural damage or discomfort for those nearby.
