降低船体振动的桨舵偏置设计方案

采用比水面船舶常规桨舵配置多一只舵或少一二只舵，通过合理布置桨舵相对位置，以降低船舶的振动和噪声、提高船舶推进效率、提高船舵控制航向的性能。此方法特别对水面船舶设计有实用价值。

Design Scheme of Propeller-rudder Biasing to Reduce Hull Vibration

By adding one more rudder to or reducing one or two rudders from the regular ship propeller and rudder arrangement, and fixing up the propeller-rudder relative position rationally, the results of reducing ship vibration and noise, improving ship propulsive efficiency and raising rudder＇s performance of controlling ship course may be obtained. The method is of practical value to the design of surface vesuls particularly.
