ship hull vibration

The effective wake is one of the primary reasons of propeller cavitation and induced ship hull vibration.

实效伴流的不均匀性是引起螺旋桨空泡、振动的主要原因之一。

Both the ship hull vibration and the local vibration of ship stern structures should be taken into consideration in the vibration problem of ship stern structures.

船舶尾部结构的振动问题应同时从船体总振动和尾部结构的局部振动两方面来考虑。

When the beam theory was used to calculate ship hull vibration, greater discrepancies were found between theoretical calculations and actual measurements especially at higher-modes.

当用梁理论计算船体振动的高谐调特性时，理论计算值与实际试验量测值有较大偏差。这样，梁理论不能作为计算高协调振动的一个实际可用的方法。
