Calculation of bearing loads, moments and stresses for shaft alignment on marine propulsion plants.
Troublefree and flexible modeling of the shaft line
Control of vibration levels and optimum shaft alignment are necessary on all ships in order to have machinery that operates with the required safety and reliability. The shaft alignment tool can be used in the early design stage or in the operating stage to investigate possible damages due to wrong alignment.
The program has several useful features where it is possible to find the exact bearing positions based on traditional verification methods such as jacking or strain gauge measurements.
Shaft alignment, whirling and axial vibration calculations are traditionally regarded as three much separated mathematical problems. Nauticus Shaft Alignment simplified your analysis process by integrating the three mentioned calculation methods into one common user interface and reporting tool.
Nauticus Shaft Alignment provides all necessary results for shaft alignment procedures:
