Description
Technical field
The present invention relates to ship machinery technical field, more particularly to a kind of damper installation capability control method.
Background technology
The damping technology used in modern ships Machine Design is mainly to be realized using damper, and effectiveness in vibration suppression needs
Ensured to realize by rational mounting process technology.According to the application of real ship damper the results show that same mechanical operating is set
Standby, in the case where installation approach is almost the same, vibration difference is larger, this illustrates the installation capability control work of equipment damper
Skill has a great impact to the vibration of mechanical equipment, it is therefore desirable to carry out grinding for equipment damper installation capability control process
Study carefully work.To promote the installation effectiveness in vibration suppression of damper, it is horizontal to reduce vibration equipment.
Invention content
The present invention provides a kind of damper installation capability control methods.This method is solved by damper performance change
The technical issues of damper control method.
Scheme is used by the present invention solves technical problem：
Damper deflection when to flat placed type, side hanging, the installation of suspension type equipment damper, damper stiffness value, spacer thickness,
The laboratory test verification work of damper mounting surface contact area, bolt fastening procedure factor.
The first step, to being ranked up from small to large by Static stiffness to the damper of the same model of factory；
Second step is ranked up the equipment for using sequence model damper by vibration acceleration size；
Third walks, and is ranked up from big to small to the vibration acceleration of equipment under-chassis；
Then it is big to be distributed to the big equipment Acceleration of vibration acceleration by the 4th step from small to large by Static stiffness for same model damper
Under-chassis；
5th step, and so on complete salty same model damper share out the work；
6th step installs damper by normal damper mounting process.
Good effect, the present invention is by selecting homotype damper, sorting, first, by the small damper of Static stiffness for leading
Vibratory equipment is wanted, two are to try to the small damper of Static stiffness for vibrating big equipment under-chassis.Damper is promoted to greatest extent
Vibration isolating effect.The equipment mounting dampers technique is optimized, and increases damper screening link, makes equipment vibration isolating effect
It is promoted to greatest extent.Suitable for as vibration-reducing control method application.
Specific implementation mode
The specific implementation case of the present invention is set forth below.
Case study on implementation：
Installation capability control process implementation is carried out so that certain ship damper is installed to factory as an example to be described as follows：
The first step, to being ranked up from small to large by Static stiffness to the damper of the same model of factory；
Second step is ranked up the equipment for using sequence model damper by vibration acceleration size；
Third walks, and is ranked up from big to small to the vibration acceleration of equipment under-chassis；
Then it is big to be distributed to the big equipment Acceleration of vibration acceleration by the 4th step from small to large by Static stiffness for same model damper
Under-chassis；
5th step, and so on complete salty same model damper share out the work；
6th step installs damper by normal damper mounting process.
Being transmitted on vibration equipment influences the research of correlation rule, extracts a large amount of mounting dampers running device conducts of real ship
Research object, wherein wind turbine 10, pump 7；Horizontal, hanging, pendant installation are respectively 7,9,1；Damper EA types 48
Block, 20 pieces of BE types.Vibration-testing data and technological parameter when through to above equipment and damper normal work are divided respectively
Analysis；
Find that each under-chassis vibration dispersion of equipment is big on the same stage according to experiment；Equipment homotype damper on the same stage, Static stiffness it is smaller then every
The better feature of effect of shaking.Existing damper is selected at random according to model and has carried out process modification, existing damper is installed
The damper of technique is selected, sequence link optimizes, first, when homotype damper screens, the small damper of Static stiffness is used
In principal vibration source device, second is that by the small damper of Static stiffness for vibrating big equipment under-chassis.
