Below calculator could be used to perform balancing calculation for more than one plane.

ROTOR BALANCING — LEAST-SQUARES INFLUENCE COEFFICIENT METHOD

Multi plane Dynamic Balancing Calculator

Enter the unbalanced vibration reading, then one trial run per correction plane. The solver builds the influence-coefficient matrix and computes correction weights by least squares.

01

Configuration

A measurement point is one vibration pickup / phase reference location. You need at least as many measurement points as correction planes.

02

Initial (unbalanced) run

Vibration amplitude and phase at each measurement point, before any trial weight is added.

03

Trial runs

Add one trial weight at a time — record vibration at every measurement point, then remove it before the next plane's trial.

Correction weights

Influence coefficient matrix

Predicted residual vibration after correction
