Detailed description of the invention
Fig. 1 is the structural schematic diagram of present pre-ferred embodiments.
Specific embodiment
A preferred embodiment is named, and completely illustrates the present invention in conjunction with attached drawing to become apparent from.
As shown in Figure 1, a kind of two-way trailer-type model test apparatus comprising trailer 10；First is equipped with below trailer 10
Ship model 21 and the second ship model 22.First ship model and the second ship model are in longitudinally spaced distributions.
The tail portion of second ship model 22 and the tail portion of the first ship model 21 are oppositely arranged.
The movement of the longitudinally asymmetric center line of first ship model 21, the longitudinally asymmetric center line of the second ship model 22 and trailer 10
Direction is overlapped.
It is installed with the first fixed device 31 on first ship model 21, the second fixed device 32 is installed on the second ship model 22, the
One fixed device 31 and the second fixed device 32 are affixed by connecting component (being not shown on figure) and trailer 10 respectively.
First fixed device 31 is equipped with the first dynamometer 41, for measuring the test data of the first ship model 21；Second is solid
Device 32 is determined equipped with the second dynamometer 42, for measuring the test data of the second ship model 22.
First fixed device can be one, which is set to the centre of the first ship model.Second fixed device
It can be one, which is set to the centre of the second ship model.In this way, component is few, manufacturing cost is low.
In the present embodiment, the first fixed device 31 is two, one of them is set to the bow of the first ship model 21, in addition one
A stern for being set to the first ship model 21.
In the present embodiment, the second fixed device 32 is two, one of them is set to the bow of the second ship model 22, in addition one
A stern for being set to the second ship model 22.
The present invention can carry out resistance test.When resistance test, the stroke of trailer includes backhaul and backhaul.When backhaul, drag
Vehicle 10 drives the first ship model 21 mobile, 41 real-time data collection of the first dynamometer, the console being transmitted in trailer 10.Backhaul
When, trailer 10 drives the second ship model 22 mobile, 42 real-time data collection of the second dynamometer, the console being transmitted in trailer 10.
Without installing propeller, self-propulsion test then needs to install propeller and rudder resistance test.
The tail portion of first ship model 21 is equipped with the first rudder 51 and the first propeller 61, and the inside of the first ship model 21 is equipped with driving the
The first motor 71 of one propeller 61；The hydrodynamic(al) force data for measuring the first propeller 61 is connected on first propeller 61
First pump dynamograph 81；First pump dynamograph 81 is set to the inside of the first ship model 21.
The tail portion of second ship model 22 is equipped with the second rudder 52 and the second propeller 62, and the inside of the second ship model 22 is equipped with driving the
Second motor 72 of two propellers 62；The hydrodynamic(al) force data for measuring the second propeller 62 is connected on second propeller 62
Second pump dynamograph 82；Second pump dynamograph 82 is set to the inside of the second ship model 22.
When self-propulsion test, the stroke of trailer includes backhaul and backhaul.When backhaul, the first motor 71 of the first ship model driving the
One propeller 61, the hydrodynamic(al) force data of the first propeller 61 are transmitted to the console in trailer 10 by the first pump dynamograph 81.Backhaul
When, the second motor 72 of the second ship model drives the second propeller 62, and the hydrodynamic(al) force data of the second propeller 62 is by the second pump dynamograph
82 are transmitted to the console in trailer 10.
In the present invention, the first ship model and the second ship model are equipped with below trailer simultaneously, two ship models are acquired with independent data
System is not interfere with each other.First ship model and the second ship model longitudinal direction tail arrange tail, fixed by the first fixed device and second respectively
Device is fixed in trailer.Certain fore-and-aft distance is kept to interfere between first ship model and the second ship model to avoid flow field.
When backhaul, the first ship model is measured, the second ship model is without measurement；When backhaul, the second ship model is measured, the first ship model is not necessarily to
Measurement so recycles.
When backhaul, trailer drives the first ship model mobile, the first dynamometer and the first pump dynamograph real-time data collection.Backhaul
When, trailer drives second ship mould mobile, the second dynamometer and the second pump dynamograph real-time data collection.
Compared with existing trailer unidirectional measurement system, the present invention back and forth can be measured two ship models at one, work
It is obviously improved as efficiency, efficiently solves the contradiction of ship model experimental tank working days anxiety.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
Modification each falls within protection scope of the present invention.
