Description
Technical field
It is that one kind changes to existing ship model test towing tank measuring apparatus the present invention relates to a kind of intelligent seaworthiness instrument apparatus of cable type
That makes is useful in the novel ship hydrodynamic performance measurement apparatus of lake or reservoir.
Background technology
Ship model test towing tank is a kind of equipment of hydrodynamics experiment, can generally carry out ship model resistance test, be tried from boat
Test, the fluid correlation test such as seakeeping test and propeller open-water test.Basin test environment and scale size are confined to, is tested
, it is necessary to analyze scale effect and Reynolds number effect during data processing, i.e., when carrying out ship model experiment, it is impossible to meet all similar
Criterion all conditions equal with real ship, can only achievement unit split-phase seemingly, cause model test result to be produced when calculating real ship performance inclined
Difference.
When carrying out the hydrodynamic tests such as rapidity, sea-keeping in rectangle pond, limited by pond yardstick, test tape can be given
Come many not enough：1. model can only be implemented to head sea in this pond, have speed trial under stern sea operating mode；2. for yardstick slightly
, it is necessary to consider the interference that pool wall is reflected model wave making in experiment for large-sized model；3. the trailer side bridge above model can be to big
The motion amplitude of Scale Model brings limitation, and the speed of model is usual by trailer control, and the travel speed of trailer has scope
Limitation；If 4. the yardstick of model is too small, the reynolds number Re and real ship difference of experiment can be caused excessive, and have a strong impact on test measurement
Precision；5. pond wave maker simulated waves is limited in one's ability, and it is unidirectional, pseudorandom, push pedal generation wave to make wave,
There is very big difference with actual wave；
Carry out related ship performance experiment in pond, not only experimental enviroment has very big difference with true wave environment,
And influenceed by factors such as pond wave maker function, pond size, wall constraints, measurement data and grinding under true environment can be made
Studying carefully data has very big difference, or even can produce the result completely contradicted, and has a strong impact on the purpose and meaning for carrying out experiment.While by
Pool environment is limited, and the conceptual design to model brings many constraints and difficult so that many real ship features in experiment are in water
Can not truly it be reflected in pool model experiment.Experiment limitation in view of ship towing basin and build pond it is expensive into
This, a kind of intelligent seaworthiness instrument apparatus of novel cable formula of transformation ship model test towing tank suitable for lake of invention.
The content of the invention
The invention aims to provide a kind of cable type intelligent seaworthiness instrument apparatus, it is easy to manufacture, use and grasp
Facilitate, measurement experiment result is more accurate, and test performance is more excellent, ship model test towing tank can be made up because of yardstick and experimental enviroment
Cause error of measured data problem.
The object of the present invention is achieved like this：Including being arranged on two height-adjustable pillars on waters both sides, dividing
Hoist engine that An Zhuan be on two pillars, the cable being arranged between two hoist engines, the lower end of underlying cable is set
Support is equipped with, the lower end of support, which is provided with ship model, support, is provided with measuring apparatus.
Present invention additionally comprises some such architectural features：
1. the hydraulic pressure launching and recovering equipment for adjusting height is provided with each pillar.
2. described in support be cylindrical rod piece, and the lower end of support and the midline position of ship model are connected.
3. described in the distance between measuring apparatus and ship model deck be 0.5 meter, between measuring apparatus and the cable of lower section
Distance is 1.5 meters.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention carries out phase in the true waters such as lake, reservoir
Close ship hydrodynamic performance (such as Ship Resistance, ship seakeeping, ship from navigate, propeller open-water test) test.According to lake
Pool or reservoir size, choose the devices such as suitable pillar, hoist engine and cable.Cable type intelligence seaworthiness instrument apparatus is in actual water
Carry out hydrodynamic test under domain, can further reduce ship towing basin because of influence of the scale effect for test result, may be used also
Hydrodynamic performances response characteristic of the ship model in true environment is studied, the hydrodynamic performance of real ship is more conformed to.And experiment
The wave met with is the effect by wind and gravity and the short-crested wave wave under the true environment that produces, by rationally designing a model,
It can analyze and handle ship strong nonlinearity motion (nonlinear motion, load, slamming and upper wave etc.) and wave load analysis yardstick
The influence of effect；Consider the synergy of stormy waves stream and carry out and analyze flow field and fluidised form change around ship model under actual environment
Change situation, to reach the influence for reducing Wake Field scale effect to ship performance；The utilization ratio of device is high, can carry out big absolutely
Most hydrodynamicangle experiments, including：Sea-keeping, resistance and propulsive performance etc., can carry out the correlative measurement for the fine flow of ship
Amount, understands propeller exciting force, vacuole, the scale effect of noise in depth, proposes rationally effective Improving Measurements.Cable type intelligence
Seaworthiness instrument apparatus can both avoid the equipment such as high pond boat car, the wave maker of construction cost, and test under true environment
Carry out, measurement data is more nearly truly, and reliability is higher, has very important meaning for ships hydrodynamic performance
Justice, application prospect is very wide.
