A fast multi-plane shaft balancing method with adaptive features

The procedure for dynamic shaft balancing in one plane is quite well known. Multi-plane balancing is more complex. In production, it is most important to minimize the average number of measurements needed to perform balancing while fulfilling the requirement for residual imbalance. A novel method has been developed taking these aspects into account. By using a priori information about the system together with linear system theory, namely making assumptions about linear and stationary transfer functions, the balancing procedure can be greatly improved. Time is a very important factor in industy, and the balancing time was decreased by a factor of four with this novel balancing method. All the results acquired during the balancing process can be used to update the linear system model, thus giving the approach adaptive features. This enhances the performance even more. This method is applicable to multi-plane balancing.
