Description
Technical field
The present invention relates to vibration and noise reducing field more particularly to a kind of eight sufficient thrust bearing pedestals of hydraulic-driven.
Background technique
Currently, ship equipment damping property as measure modern ships comprehensive performance an important indicator increasingly by
Extensive concern.Excessive ship hull vibration can lead to Ship Structure and generate fatigue rupture, will affect equipment on board and instrument just
Often work reduces precision, shortens the working life；Furthermore ship hull vibration and its caused cabin noise also influence crewman and tourist
Comfortable for living.When fatigue can be generated in the environment that people are chronically at vibration, working efficiency is influenced, or even jeopardizes body and is good for
Health；The vibration of ship also brings along certain seanoise environmental pollution simultaneously.Study effective ship equipment damping element tool
It is significant.
In addition, misaligning failure is one of major failure of rotating machinery.It misaligns and refers to that driving shaft and driven shaft do not exist
On straight line.Marine propulsion shafting is the core component for transmitting power, and the working condition of shafting is directly related to the work of whole ship
Make performance.The superiority and inferiority of shafting alignment quality has the normal operation and reduction ship hull vibration and energy consumption that ensure shafting and host
Great influence.
For this purpose, center line not coincidence error and gradient are reduced as far as possible in shafting installation and maintenance, it is this to subtract
The operation of few not coincidence error and gradient is known as shafting alignment correction.Currently, shafting alignment correction main method have ruler method,
Dial gauge method, laser alignment method, foil gauge measurement method etc., but these types of method has certain limitation, and method is complicated, behaviour
It is inconvenient to make, and takes a long time, professional is needed to measure.
Meanwhile mainly using passive control system more thrust bearing pedestal vibration damping at present, reason for that is in addition to quilt
Except the factors such as the reliability height of dynamic vibrating isolation system, it is also necessary to consider the factors such as the characteristic of exciting force.But passive vibration isolation is low
The effect of frequency range is poor, therefore low-frequency range high performance control is realized using active control.And main passive mixing control, it is incorporated in
Medium-high frequency section realizes effective vibration isolation to vibration source in the method that low-frequency range uses active control using passive control.
The defect of the prior art is: such is using more rare, existing shafting alignment in document at home and patent
Bearing calibration adjustment difficulty, bad adaptability, passive snubber base low-frequency range effectiveness in vibration suppression is bad, flexibility ratio is not high.
