Enough complete the dynamic experiment of underwater immersed body compound movement form.
Background technology
Carry out underwater immersed body dynamic experiment using towing experimental provision, be the important of research underwater immersed body dynamicss
Means.Current towing experimental provision mainly has two kinds of forms, and one kind is winch towing type, that is, using the strand installing pond two ends
The mode that car is drawn to underwater immersed body；Another kind is trailer towing type, will underwater immersed body be arranged on trailer, trailer exists
Moving on rails, thus drive underwater immersed body to move under water.But both towing experimental provisions are currently used primarily in measurement water
The resistance of motion of diving body, can only drag underwater immersed body and simply be moved along a straight line.Wherein, the former is from the design of experimental system
It is impossible to dragging underwater immersed body for itself and complete more complicated forms of motion；By the way of the latter adds track using trailer,
There is a possibility that dragging underwater immersed body completes compound movement form in theory.But due to carrying out underwater engine experiment, need
Meet the requirement of the factor precise controls such as the athletic posture to underwater immersed body, movement velocity, the therefore towing of trailer towing type is real
Experiment device completes underwater immersed body compound movement dynamic experiment needs to solve following two problems: one is to be subject to during underwater immersed body motion
To the resistance of water, and pass it to drive the dolly of underwater immersed body motion, make dolly be difficult to keep balance；Two is trolley
Can collide with orbit sidewall in motor process, this two problems all can have influence on the athletic posture of underwater immersed body, motion speed
Degree, thus affect the accuracy of experimental result.
