Abstract
A method for determining an imbalance of a propeller shaft assembly can include establishing balancing planes relative to certain areas of the propeller shaft assembly and identifying each component of the propeller shaft assembly that could have a potential imbalance condition due to a tolerance variation. The method can also include determining the potential imbalance condition for each identified component, and determining a contribution of each determined potential imbalance condition to a respective pair of the established balancing planes. The method can further include determining a total magnitude of imbalance at the respective pair of established balancing planes based on the determined contributions of each potential imbalance condition, and determining a statistically representative value of the determined magnitude of imbalance.
