Hull vibration is the vibration generated by the sailing ship due to various reasons. 90% of the vibration on the ship comes from the pulsating pressure of the propeller, which can generate the stern vibration, superstructure vibration and local vibration. Especially in the area above the propeller, the propeller pulsation pressure often causes local structural resonance or forced vibration, resulting in structural fatigue damage or reduced living comfort. It is therefore necessary to reduce the vibrations caused by the pulsating pressure of the propellers. However, in the early stage of the propeller design, it is not convenient to calculate the pulsating pressure of the propeller due to the complexity of the calculation method. It is important to design a software that can quickly estimate the pulsating pressure of the propeller. In the current study, a software for the rapid estimation of the pulsating pressure of propellers is developed by using the empirical formulas with a mixture of QT and MATLAB programming, to discuss the influencing factors and variations of the pulsating pressure. The results show that the shape parameters of the ship section, the type of the ship and the rotation speed of the propeller greatly affect the pulsation pressure of the propeller. It can provide references for the ship vibration and noise reduction.
