摘　　要：现代船用柴油机广泛采用废气涡轮增压器。新造船舶在进行主机系泊试验时,有可能发生主机增压器压气机喘振的现象。本文基于某船在系泊试验过程中出现的增压器喘振现象,通过实船螺旋桨轴扭矩的测量数据及推进特性曲线分析,找出引起增压器喘振的主要因素,并提出在系泊试验时的具体规避方法。Exhaust gas turbochargers are widely used in modern marine diesel engines.During the mooring test of the main engine on a newly-built ship,the surge phenomenon of the main engine supercharger compressor may occur.Based on the turbocharger surge phenomenon of a ship during the mooring test,this paper finds out the main factors causing the turbocharger surge through the measurement data of the propeller shaft torque of the real ship and the analysis of the propulsion characteristic curve,and proposes a specific avoidance method during the mooring test.
