Embodiment
The present invention can continuously change in the water at anchor cable inclination angle the suspension tunnel model test unit and comprise slidably suspension tunnel model and anchor cable in base, top-support and the water.
As shown in Figure 1, 2, slidably base comprises base 4, is arranged on the guide rail 5 on the base, and the slide 7 that can move on guide rail is fixed on pulley 3 and rotation drive machine on the slide 7.Slidably base should have enough weight, can be in water be moved under the anchor cable pulling force effect of submerged floating tunnel test model to guarantee base in test.And, slidably the pedestal 4 of base and guide rail 5 should be selected suitable length according to the anchor cable inclination angle scope of the required adjusting of test, slidably the guide rail 5 of base can be divided into left side and right-hand part by position in the middle of it, two parts are provided with the screw thread that sense of rotation is opposite, pitch is identical, and are provided with screw thread with matching in slide 7 inside.Two slidably slides 7 of base are set in the experimental provision, and its length should be not less than suspension tunnel model length in the water, be not more than the experimental trough width.Two slides 7 are installed in guide rail the right and left symmetrically.Gear train is made up of control lever 6a, gear and connecting rod.
Shown in Fig. 3,4, top-support comprises base 9, be arranged on leading screw 10 and the transmission height adjustment mechanism 11 that is arranged on the leading screw 10 on the base 9, the crossbeam 14 of top-support, be arranged on the snap ring 15 that is used for fixing anchor cable 2 tops on the top cross-bar, top-support should have enough rigidity, does not influence experiment measuring bigger distortion can not take place under the tension force effect that guarantees support suspension tunnel model anchor cable in water.
The shape of suspension tunnel model, size, material etc. customize according to testing requirements.The buoyancy of suspension tunnel model is greater than self gravitation in the water, and by anchor cable balance surplus buoyancy, anchor cable is slidingly connected by pulley on the slide and base, and extends the water surface, and the end is fixedly connected on the top-support.
During experiment, shown in Fig. 1,2,3,4,5, top-support is arranged on the experimental trough edge 13 by its base 9; Slidably base is placed on the experimental trough bottom, and suspension tunnel model 1 is fixing by anchor cable 2 in the water; Anchor cable 2 lays out the water surface 8 through pulley 3, and the anchor cable end uses snap ring 15 to be fixed on the crossbeam 14 of top-support.When needing in the experiment to change the anchor cable inclination angle, drive guide rail by the control lever 6a of rotational fixation on the tank edge by gear and rotate, on guide rail 5, move to the guide rail both sides or to guideway centreline symmetrically thereby drive two slides 7.There is reflection to rotate the gauge point of the number of turns on the control lever 6a, the anchor cable inclination angle of in experiment, realizing accurately changing empirical model by the rotation number of turns of controlling control lever 6a.Because the total length of this test unit stream line is fixed, in the inclination angle that changes anchor cable 2, should correspondingly regulate support height, to guarantee that suspension tunnel model 1 underwater depth of immersion is constant in the water.Support can be regulated height by producing relative motion between rotation height adjustment mechanism 11 and the leading screw 10.The anchor cable end of empirical model is fixed on the crossbeam 14 of top-support with snap ring 15.Can on snap ring 15, measure tension force in the anchor cable by the installing force sensor.
