Do We Have to Place the Dynamic Balancing Machine on a Foundation Structure?

Placing the dynamic balancing machine on a solid foundation is absolutely essential, a critical step that directly affects the machine's performance, measurement accuracy, and longevity. A balancing machine detects even the slightest vibrations caused by the rotating part and calculates the remaining unbalance based on these vibrations. If the machine itself is subjected to vibrations or vibrations caused by external factors, this will distort the measurements and lead to erroneous results. Therefore, the ground on which the machine will be installed must be vibration-free, stable, and stable. Otherwise, the signal from the part's unbalance will be mixed with environmental noise and vibration, making accurate analysis impossible.

A solid foundation allows the machine to absorb its own weight and any dynamic loads that may occur during operation, enabling measurement systems to operate with the highest precision. This is also crucial for occupational safety. At MBS Balance, we place great emphasis on this fundamental principle during the installation of our machines. We provide our customers with technical support regarding the proper ground preparation for the efficient and accurate operation of their machines. A balancing machine mounted on a correct foundation not only provides precise results, but also reduces the need for maintenance and extends operational life.

Two criteria are decisive in the foundation design: mass and vibration isolation. In machines that balance heavy rotors, choosing the foundation mass as several times (commonly 3-5 times) the combined mass of the machine and the heaviest part ensures that dynamic loads are damped. In addition, the natural frequency of the foundation must be kept away from the balancing speed range; otherwise the foundation itself enters resonance and contaminates the measurement.

The floor must be isolated from vibrations caused by nearby presses, cranes, or traffic; if necessary, vibration isolation mounts or a separate mass block (inertia block) should be used. Errors in the machine's leveling and in the anchor torques also degrade repeatability. MBS Balance calculates the floor and foundation requirements before installation according to the part's speed and mass and provides the customer with a technical specification; thus the machine's catalog precision is also achieved in the field.
