Abstract

The invention discloses a vibration characteristic test system of a diesel engine propulsion system. and the transmission device are arranged on the simulation base; the air spring height control assembly is used to support the hull simulation base to isolate external vibration. The air spring height control component of the test system can provide softly supported boundary conditions for the hull simulation base, thereby isolating external vibrations.

Description

technical field [0001] The invention relates to the field of test systems for ships, in particular to a vibration characteristic test system of a diesel engine propulsion system. Background technique [0002] Diesel engine is the main equipment commonly used in ships. After the diesel engine transmits its power to the propeller through the propulsion shaft system, it will generate thrust, and the thrust will act on the hull structure through the thrust bearing. [0003] The thrust generated by diesel engines, gearboxes, propellers and other equipment in operation will induce vibration of the hull or equipment-related structures and radiate noise. Even if the diesel engine propulsion system has vibration reduction measures, the structural vibration caused by the dynamic force excitation of the propeller will become more and more significant. Therefore, technicians need to study the contribution of diesel engine, transmission and propeller thrust to the vibration response of ...
