TrimBal
TrimBal is a tool to perform trim balancing on rotating equipment. Features are:
- Intuitive user interface – The user can view the setup and data in a single table. Points can be annotated and manipulated with simple controls.
- Unlimited number of probes and planes
- Trim weight split solver – When fixed trim weights are used TrimBal can solve for optimum weight placements. Solutions are shown for progressively greater numbers of weights up to a user defined maximum.
- Graphical trim weight management – Weight solutions are plotted and the user can easily visualize the affect of adding or subtracting fixed, or custom ground weights.
- Four run solver – When no key phasor is available a single probe, single plane four run solver is provided.
- Influence coefficients – The “.icf” file format is used, which is compatible with some other trim balance programs.
