Nautcus Machinery Torsional Vibration analysis software

Torsional vibration analysis

The Torsional Vibration calculation software helps you control vibration levels in your engines, propulsion systems and generator sets.

Torsional vibration software

  • Easy, reliable and effective software for marine shafting systems
  • Calculates free or forced vibrations for all types of ship engines and propulsion plants
  • Handles ice impact on propeller by steady-state approach
  • Supports almost all marine propulsion systems, including direct coupled propulsion systems, geared propulsion systems and generator sets
  • Analysis of wide range of ship and small craft engines such as: 
    - Conventional diesel driven plants (gear or direct coupled), single or multi-branched
    - Recreational size marine engines such as inboard and sterndrive engines, including transmission and driveline configurations
    - Gas turbine plants
    - Water jet plants
    - Diesel electric plants
    - Generator sets

Control of vibration levels with torsional vibration calculations software

Keeping control of vibration levels in your engines, propulsion systems and generator sets is essential in order to have machinery that operates safety and reliably. The wrong combination of individually satisfactory components may lead to an inappropriate system. The Torsional Vibration calculation software can identify the interaction between components, an essential part of the system and functionality assessment.

Key benefits of the Torsional Vibration software module

  • State-of-the-art graphical user interface with flexible modelling options
  • Support for Windows XP/7, 32- and 64-bit platforms
  • Enhanced mathematical algorithms based on well-proven technologies
  • Tailor-made user dialogs available for calculation of complex parameters such as cylinder pressures, propeller damping or entrained water 
  • Integrated component libraries for engines and couplings
  • Upload- and download excitation data files for diesel engines (engine harmonics)
  • Exchange of models, results and reports supported by web services
  • No pre- or post-processing, all operations are carried out in one interface
  • No practical limitation with respect to number of masses or shafts
  • Advanced report and print features, integration with MS Office applications
  • Identifies the steady state response amplitudes of stress, torque and dissipated power in different elements at various torque-load conditions due to external excitation
