Multi-plane Balancing analyzes the baseline vibrations and then the vibrations from adding a trial mass (inertia) at each balance plane in turn. The software guides the user throughout the entire process. These measurements enable influence coefficients to be calculated. A least squares optimized multi-plane balancing algorithm using a single value decomposition algorithm (SVD) with an option to add bias forms the mathematical heart of the software.

Once the influence coefficients are known the software predicts the masses required to achieve a zero imbalance or some user specified imbalance. This is particularly useful as a ‘worst of class’ case to verify if that level of vibration affects the chosen quality criteria. Test runs at these conditions may be made giving the actual weights added to compare the predicted and achieved results.

The user interface is designed to automate repetitive testing, taking the user through the necessary steps to perform the baseline capture and trials capture.

Shaft configurations may be set up and saved containing such details as balance plane name, radius, preferred trial weight and split weight locations.

A pre-balance run-up allows identification of the ideal shaft speed to perform balance. Signal quality checks are also provided to detect overranging, bad tacho signals and out of band speeds. The time history and the first order component for each input signal may be displayed to assist the user in accepting or rejecting the current measurement.
