About Vibra Calc

Vibra Calc calculates vibration frequencies of rotating machinery components given the specifications of each component. It includes induction motors, gears, rolling element bearings, pumps, fans & blowers, journal bearings, and belts & pulleys. Also, it provides an interactive vibration severity test tool based on the ISO 10816-3 standard. Furthermore, Vibra Calc has a calculator for vibration conversions from/to displacement, velocity, and acceleration with metric and imperial units.

Features:
- Induction Motor Frequency Calculator
- Full detailed gears frequencies (main, harmonics, sidebands) up to 4X
- Rolling element frequencies (BPFI, BPFO, BSF, FTF) given the bearing dimension or the bearing model number
- Pump vane pass frequencies up to 4X
- Fans blade pass frequencies up to 4X
- Journal bearing frequencies corresponding to wear and oil whirl phenomena presented in a table and over an interactive chart
- Belt frequencies up to 4X
- Interactive Vibration Severity Test Tool based on ISO 10816-3 (INPUTS: vibration velocity in mm/s or inch/s, type of support, type of machine & OUTPUTS: Machine Operation Condition)
- E-mail and Save the screen option for vibration severity tool
- Vibration calculator to convert displacement/velocity/accelerations to each other (Metric & Imperial)
- Vibration Glossary
