摘要：为了研究节能附体对螺旋桨空泡脉动压力的影响，进行了带节能附体螺旋桨空泡脉动压力的试验研究。在相同的船模伴流场、推力系数和空泡数工况下，测量了浆模、浆模带节能导管和浆模带节能支架时的螺旋浆脉动压力，计算得到螺旋桨脉动压力系数，并换算成实桨脉动压力值。研究并观察记录了相应的螺旋桨空泡形态。试验结果表明，节能导管和节能支架能有效减小螺旋浆脉动压力，减弱或消除毅涡，削减螺旋浆片空泡发生范围；带
节能支架的端施浆空泡脉动压力性能优于带节能导管的螺旋。关键词：节能附体；空泡；脉动压力；节能导管；节能支架

Abstract: The model tests of propeller induced cavitation and the pressure pulses with the energy-saving appendage were con ducted to study the effect of energy-saving appendages on them, Propeller induced pressure pulses are measured with or without the energy-saving duct/energy-saving holder in the same ship-model wake field under the same Kr and o. The fluctuating pres-sure coefficient and the pressure pulses in the full scale are derived. Three of the main influence factors are studied in the SSSRI cavitation tunnel, Cavity patterns are recorded, The test results show clearly that energy-saving duct/ holder can reduce or e-liminate boss vortex and cut down the sheet cavitation extent, hence, reduce pressure pulses effectively. The experiments also show that cavitation and pressure pulse performance of the propeller with energy-saving holder is better than that with energy saving duct.

船舶节能已成为世界各国造船界和航运界的重要课题，船舶推进附加节能装置是实现船舶节能的有效
措施之一。水动力方法研制的船推进附加节能装置主要有两大类：一类装在螺旋桨前，以改善螺旋桨的毅帽鳍、能球等。
为了研究船舶节能装置对螺旋浆诱导的空泡脉动压力的影响，进行了带节能附体螺旋桨空泡脉动压力的试验研究。研究的节能附体为前置节能导管和节能支架。在相同的船舶伴流场、推力系数和空泡数工况下，对浆模、柴模带节能导管和桨模带节能支架时的脉动压力进行测量，计算得到脉动压力系数，并换算成实
