Description
Technical field
The utility model relates to wind tunnel experiment modelling technique field, specifically the complete gas bullet wind tunnel experiment model of a kind of angle iron component lattice tower.
Background technology
Lattice tower structure (communications tower, electric transmission pole tower and television tower etc.) belongs to a kind of of tower mast structure, is a kind of version that is widely used in lifeline engineering.This class formation has played very important effect to the transmission of TV, communication signal and electric power.The destruction of power transmission tower frame can cause the paralysis of electric power system, and this can have a strong impact on people's orders of life, the production and construction of factory, but also can produce great secondary disaster (such as fire etc.), cause serious consequence for society and people's lives and properties.
Because lattice tower has lightweight, Gao Rou, the characteristic of little damping, under high wind and geological process, its structure can produce violent vibration, cause the rod member fracture or stay residual deformation, even total also might be blown down by wind load or Earthquake falls, particularly the height along with lattice tower constantly increases, wind load has become its main control load, research means for the lattice tower wind load mainly relies on wind tunnel experiment, rationally effectively the wind tunnel experiment model is the important foundation that obtains reliable data, the wind tunnel experiment model mainly is rigid model at present, this class model can't be simulated the aeroelasticity effect of structure and flow field in the actual wind field, and at present existing some gas bullet models (the semi-rigid gas bullet model that uses spring leaf to be formed by connecting such as the sectional rigid model) can not satisfy the Basic Physical Properties to true pylon, especially to quality, the real simulation of rigidity space distribution, so " fully " aeroelasticity wind tunnel experiment model that a kind of satisfied and actual lattice tower ratio of similitude of designing and making requires is very important to obtain accurately effective Wind Tunnel Data.
The utility model content
The utility model mainly is for the existing technical matters of above-mentioned prior art, provide a kind of can be by design a model each member how much outer clad cans, rigidity and model weight mass with the complete gas bullet wind tunnel experiment model of the lattice tower that obtains to satisfy ratio of similitude and require, its design theory is strong, making is meticulous and be convenient to installation and maintenance.
A kind of lattice tower of the utility model is gas bullet wind tunnel experiment model fully, comprise: pylon skeleton body 1, polylith angle steel shape external application plate 2 and with the base 3 of reserving installation hole 6, described pylon skeleton body 1 rigidly connects on base 3, and angle steel shape external application plate 2 is arranged on the outside surface of pylon skeleton body 1; On the described pylon skeleton body 1, angle steel shape external application plate 2 inboard subsection setups are useful on the tinsel 4 of counterweight.
Be interrupted between the described polylith angle steel shape external application plate 2 without connecting.
The lattice tower skeleton of described pylon skeleton body 1 for being welded by capillary brass pipe.
Described angle steel shape external application plate 2 is the ABS plate.
Described base 3 is rigid base.
Described tinsel 4 is galvanized wire.
A kind of lattice tower of the utility model fully gas bullet wind tunnel experiment model has following advantage:
1, design is meticulous rationally, not only makes model similar to the structure Basic Physical Properties of true pylon at structural level, and makes model similar to each member Basic Physical Properties of true pylon in each member aspect; And prior art is not the quality of each root member of simulation, the utility model is with counterweight tinsel subsection setup, so that mass distribution is evenly avoided local mass concentration, every component quality is all similar to the actual components quality, realizes simultaneously phase Sihe gross mass similar of main member quality; Be interrupted without connection between the angle steel shape external application plate, thereby make the external application plate not participate in the integral rigidity of model;
2, can simulate well kinematic behavior and the aerodynamic characteristics of actual lattice tower structure, make model experiment can obtain comparatively true and reliable Wind Tunnel Data;
3, be welding between the pipe fitting of pylon skeleton body, be convenient to change member; The external application plate is different from the pylon skeleton body and independent the existence, so that model is convenient to repair and reuse, thereby saves the scientific experiment cost.

Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is partial structurtes schematic diagram of the present utility model.
Reference numeral among the figure: 1 is the pylon skeleton body, and 2 is angle steel shape external application plate, and 3 is base, and 4 is tinsel, and 5 is welding node, and 6 is mounting hole.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
A kind of lattice tower of the utility model is gas bullet wind tunnel experiment model fully, comprise: pylon skeleton body 1, polylith angle steel shape external application plate 2 and with the base 3 of reserving installation hole 6, described pylon skeleton body 1 rigidly connects on base 3, and angle steel shape external application plate 2 is arranged on the outside surface of pylon skeleton body 1; On the described pylon skeleton body 1, angle steel shape external application plate 2 inboard subsection setups are useful on the tinsel 4 of counterweight.
Described pylon skeleton body 1 is the accurate copper pipe of various different cross section sizes and length dimension, and sectional dimension and length dimension get by the calculating of ratio of similitude principle according to sectional dimension and the length dimension of actual lattice tower member.Then will be connected to according to the accurate copper pipe that ratio of similitude is selected the position corresponding with actual lattice tower and form the lattice tower skeleton.
Described angle steel shape external application plate 2 is the ABS plate, is interrupted between the polylith angle steel shape external application plate 2 without connecting, and the purpose of interruption is for so that its integral rigidity of parameter model not.Described angle steel shape external application plate 2 is that sectional dimension and the length dimension by actual each angle iron component of lattice tower calculates than principle by geometric similarity, forms with lightweight and less material (ABS plate) the engraving cutting bonding of distortion according to calculating the gained physical dimension.
