Embodiment Construction

[0026] The invention provides an intermediate bearing with a hydraulic loading device for a ship propulsion shafting test bench. The loading device attached to the intermediate bearing is mainly composed of a force loading hydraulic device, a force sensor detection unit, a displacement sensor detection unit, and a hydraulic loading system controller. The force-loading hydraulic device has two hydraulic circuits, which are respectively installed in the horizontal and vertical directions of the intermediate bearing on the propulsion shafting of the ship. The oil cylinder is used for loading. The two hydraulic circuits can act separately or be adjusted at the same time. The pressure sensor detects the magnitude of the pressure, and the displacement sensor detects the moving distance of the shaft, so as to realize the closed-loop control, and carry out the conventional periodic function displacement loading on the bearing to simulate the effect of the hull deformation on the propul...

Abstract

The invention relates to an intermediate bearing with a hydraulic loading device for a ship propulsion shafting test bench, the intermediate bearing mainly consists of a hydraulic loading system, a pressure sensor detection unit, a displacement sensor detection unit, a hydraulic loading control system and a hydraulic console System composition, in which: the hydraulic loading system and the frame of the intermediate bearing adopt an integrated design, so as to support the shafting of the intermediate bearing while controlling the horizontal and vertical displacement of the intermediate bearing, which is used to simulate the bearing caused by the deformation of the hull position offset. The invention can well reflect the influence of the change of the bearing position on the vibration characteristics of the shafting system, and can change the vertical or lateral position of the bearing through a hydraulic loading system, thereby dynamically simulating the deformation of the hull and analyzing its influence on the vibration characteristics of the shafting system.

Description

technical field [0001] The invention relates to the research on the dynamic characteristics of a ship's propulsion shafting system and the performance improvement of a large ship, in particular to an intermediate bearing with a hydraulic device on a ship's propulsion test bench. Background technique [0002] Large-scale, professional, intelligent, safe, energy-saving and green environmental protection are the development trends of world ship technology. my country's ship design and construction technology is developing rapidly. Large ships, such as container ships with more than 10,000 TEUs, ultra-large oil tankers, and aircraft carriers, have become important equipment for my country's development of ocean transportation, protection of ocean rights and interests, and implementation of ocean development strategies. Ship shafting is an important part of the power plant, and its reliability and stability are important guarantees for safe navigation of the ship. With the enlar...
