The operating method of vortex-induced vibration experiment is carried out using above-mentioned oceanic umbilical cord cable are as follows:
(1) bracket is fixed
After bracket is put into experimental tank, it is adjusted to suitable position, and whether horizontal using level measurement bracket, and
The extension on cross-brace frame is clamped with basin sidewall with G word folder, it is ensured that the overall stability of bracket when test prevents
Vibration；
(2) umbilical cables to be measured are installed: the universal hinge 1-1 in bottom being fixed on the screw rod being welded in support base, is screwed
After prevent it is universal hinge rotate；Then by one end of umbilical cables to be measured and the bottom is universal is hinged, then by navel to be measured
The other end with cable is connect with the universal hinge 6-1 in top；What the other end of umbilical cables to be measured was connect with the universal hinge 6-1 in top
In the process, if the distance between the universal hinge 1-1 in bottom described in the length of umbilical cables to be measured and the universal hinge 6-1 in the top compare
Close, the length that can use the screw rod being arranged on the intermediate supports platform is adjusted, if cannot meet the requirements,
Then need to adjust the height of slidable intermediate supports platform.Adjust the height of slidable intermediate supports platform specifically: root
According to the length of umbilical cables to be measured, the height of intermediate supports platform is adjusted, and according to the graduation mark on sliding slot, by the intermediate supports
Platform is adjusted on the same horizontal plane, after reaching same plane, is rotated for connecting sliding slot and the intermediate supports platform
Intermediate supports platform is fixed on the plane, completes the installation of umbilical cables to be measured by the nut of bolt two sides.
(3) top tension applies and fixes
Umbilical cables to be measured are fixed through the above steps, top tension then is applied to umbilical cables to be measured, in the present embodiment,
Using the pulley blocks using two fixed pulleys composition, high-strength nylon rope, the counterweight of several different qualities for meeting requirement of experiment
Carry out the application of top tension.Due to the friction between pulley during the experiment, the uncertainty in nylon rope direction results in top
The error that tension applies.The quality of counterweight can accurately not transform into the practical top tension being applied on model.To understand
Certainly since the presence at frictional force and nylon rope inclination angle leads to this inaccurate technical problem for pushing up tension, in the present embodiment,
It is directly hinged with umbilical cables to be measured by the way that top is universal using tensometer；The tensometer includes tensometer digital display,
The numerical value that tension can directly be pushed up, due to being directly connected to tensometer and umbilical cables to be measured, the reading of tensometer digital display
Number is that umbilical cables to be measured really push up tension values, eliminates the error generated during pushing up tension and applying, makes to push up tension
Application it is more accurate.
When applying top tension, tensometer registration is returned to zero first, is then placed on scale pan according to requirement of experiment suitable
After the counterweight of amount, the reading of tensometer is made to be less than the 1-3N for preparing to apply tension, then can use positioned at the intermediate branch
The fine tuning that the rotation for supportting the nut of platform two sides push up tension is (described to include positioned at the nut of intermediate supports platform two sides
Top nut positioned at intermediate supports platform upper and the bottom nut positioned at intermediate supports platform lower), first by top spiral shell
Mother, bottom nut unscrew, and first slowly screw top nut, and when screwing top nut, above-mentioned removable screw rod is risen with it, top
Tension can slowly become larger, and after the nut tightening of top, if actually applied top tension is greater than requirement of experiment top tension, unscrew top
Portion's nut, removable screw rod decline therewith, can make the numerical value for pushing up tension that can slowly become smaller, be adjusted slightly by rotary top nut
When pushing up tension, the quantity of application can be smaller, is easy to hold.Top tension is applied to after the numerical value of requirement of experiment, screws bottom
Model is fixed nut, passes through the extruding force and nut and intermediate supports platform between top nut and bottom nut
Between frictional force, prevent from vibrating in the shaking and umbilical cables experimentation to be measured of the horizontal direction of umbilical cables top support to be measured
Cause teetertottering for screw rod to cause top tension in experimentation that acute variation occurs, secures initial top tension to reach
The effect of numerical value.Accurately top tension can be applied in this way and ensure to push up the stability of tension, while being limited at the top of model
The shaking of horizontal direction meets vortex-induced vibration requirement of experiment.
Experimental rig provided by the utility model embodiment can accurately apply and read the numerical value of top tension；?
While counterweight applies top tension on a large scale, small-scale application is carried out using the rotation of nut, not only makes the application for pushing up tension
It is more accurate, keep operating process more simple and feasible, avoid tiny error, and realize top tension visualization and really
The accuracy of top tension is protected.And apply push up tension after can be realized good fixation, it is ensured that application it is initial
Push up the stability of tension, it is therefore prevented that caused top tensile failure problem in experimental model vibration processes.
Experimental rig provided by the utility model embodiment reduce to the greatest extent top tension apply error and
The error that bracket flow-disturbing generates, and laser positioning is utilized on this basis, it is ensured that in vertical direction after umbilical cables installation to be measured
On the same line, this meets the static(al) position shape of actual condition umbilical cables, makes to simulate more accurate.Removable sliding slot is set
Meter strengthens the accuracy of bracket and increases the scope of application of bracket.
