扭转振动应力降低控制装置、具备该装置的船舶、及扭转振动应力降低方法
摘要：
根据本发明的扭转振动应力降低控制装置（50）是用于降低在具备与推进用的螺旋桨（11）一体地旋转的推进轴系（10）、驱动推进轴系（10）的主机（20）、和具有被从主机（20）排出的排气（27）驱动的涡轮（31）且将涡轮（31）的旋转力作为动力压缩新气并将扫气（24）供给至主机（20）的增压器（30）的船舶（100）中的推进轴系（10）处产生的扭转振动应力的扭转振动应力降低控制装置，并形成为扭转振动应力为规定值以上时，降低扫气（24）的压力的结构。
摘要（英）：

A torsional vibration stress reduction control device (50) according to the present invention is used to reduce torsional vibration stress occurring in a propulsion shafting (10) in a marine vessel (100) comprising a propulsion shafting (10) which rotates integrally with a propulsion propeller (11), a main engine (20) for driving the propulsion shafting (10), and a supercharger (30) which has a turbine (31) driven by exhaust (27) expelled from the main engine (20) and which uses the rotational force of the turbine (31) as motive power to compress new air and supply scavenged air (24) to the main engine (20), wherein the pressure of the scavenged air (24) is reduced when the torsional vibration stress is a predetermined value or greater.
