The invention discloses a sliding bearing wear estimation system of a mooring leg universal joint device, and relates to the technical field of bearing wear prediction, and the wear estimation system comprises a tension measurement module which comprises a fiber bragg grating demodulator and ten fiber bragg grating strain sensors used for measuring tension strain, all the fiber bragg grating strain sensors are connected in parallel and then are connected to the fiber bragg grating demodulator. The rotation measuring module comprises nine double-shaft tilt angle sensors; the data acquisition module is used for receiving data of all the sensors according to a set period; and when the superposed abrasion loss of any sliding bearing exceeds a set abrasion threshold value, the host system gives an alarm and displays the number of the abraded sliding bearing. According to the sliding bearing abrasion estimation system and method, all the sliding bearings of the mooring leg universal joint device can be monitored in real time, the abrasion loss of the sliding bearings is calculated, and abrasion early warning of the sliding bearings is achieved.
Description
technical field [0001] The present application relates to the technical field of bearing wear prediction, in particular to a system and method for estimating sliding bearing wear of a mooring leg universal joint device. Background technique [0002] At present, the service life (ie overhaul period) and reliability of offshore single point mooring systems are largely determined by the durability and working mechanism of the interaction interface of various bearings and other key components. The mooring leg sliding bearing is an important component of the offshore single point mooring system, and it is also the main weak link that is relatively prone to failure. For mooring leg sliding bearings, due to long-term work in special environments, heavy loads, impacts, frequent and irregular commutation swings and other extreme working conditions, the interaction interface of mooring leg sliding bearings is prone to adhesive wear and gluing. , corrosion and other failures will affe...
