Abstract
The invention provides a mirror image supporting rod used for measuring main supporting rod pneumatic disturbance of a supporting model in a wind tunnel test. The mirror supporting rod comprises a supporting rod head, two connection pins and a supporting rod body, wherein the supporting rod head and the supporting rod body are located through straight openings in interference fit, and the supporting rod head and the supporting rod body are connected and locked through the connection pins which are crossed and in interference fit. The mirror image supporting rod has the advantages of being light in weight, little in modal vibration, easy to machine and low in cost.
Description
Technical field
The present invention relates to the mirror image pole in model in wind tunnel list pole belly stay system, be used for measuring in wind tunnel test the main strut aerodynamic interference amount of bolster model.
Background technology
In model in wind tunnel list pole belly stay system, existence due to the main strut of bolster model, the test figure that model in wind tunnel self records can produce certain interference volume, when the data in later stage are processed, must be with this interference volume deduction, the effect of mirror image pole is exactly the interference volume of measuring main strut.
Need satisfy following condition during the design of mirror image pole:
(1) profile of mirror image pole need in full accord with the main strut profile, to be used for the aerodynamic interference amount of analogue measurement main strut;
(2) be a cantilever design after installing on model supporting system due to mirror image pole, sole mass should be as far as possible little, avoids producing larger modal vibration;
(3) syndeton of balance sleeve on syndeton, main strut and the model supporting system of balance sleeve on mirror image pole and model supporting system, both should be in full accord, to satisfy interchangeability, the assurance model in wind tunnel can be realized smoothly standing up assembling and support.
This mirror image pole generally adopts steel to forge the whole machine-shaping of material at present.Because whole mirror image pole is steel structure, quality is larger, and the modal vibration that self produces during test is compared with the vibration of main strut, and is relatively large, and this can bring certain error to the measurement of main strut aerodynamic interference amount; Moreover, because the mirror image pole size of global formation is larger, complex contour is forged equipment such as expecting to utilize the large-tonnage forge press and is carried out the blank making, sharp processing need to utilize the sophisticated equipments such as five-axle number control machine tool to process, and this has increased the processing and manufacturing cost greatly.
Summary of the invention
Based on above weak point, the present invention discloses the mirror image pole in a kind of model in wind tunnel list pole belly stay system, is used for measuring in wind tunnel test the main strut aerodynamic interference amount of bolster model.
The technical scheme that adopts of the present invention is as follows: a kind of mirror image pole, comprise pole head, two connecting pins and strut members, pole head and strut members position by the straight mouth of interference fit, and the pole head is connected locking by the connecting pin of two right-angled intersection interference fit with strut members.
The present invention also has following feature:
1. described pole head is steelwork.
2. described strut members is the alumiaum article of thin wall hollow.
3. the main strut profile of the profile of mirror image pole and bolster model is in full accord.
This mirror image pole has advantages of that quality is light, modal vibration is little, easily processing and cost low.
Description of drawings
Fig. 1 is the structural representation of mirror image pole.
Embodiment
Enumerating example below in conjunction with Figure of description is described further technical scheme of the present invention:
Embodiment 1
As shown in Figure 1, a kind of mirror image pole comprises pole 1, connecting pin 2 and strut members 3.Pole 1 and strut members 3 are agent structure, pole 1 is steelwork, the syndeton of balance sleeve on pole 1 and model supporting system, and both are in full accord, satisfied the interchangeability requirement, guaranteed also that simultaneously model in wind tunnel can realize smoothly standing up assembling and support; The main strut corresponding part profile of the profile of strut members 3 and bolster model is in full accord, strut members 3 is the alumiaum article of thin wall hollow, why adopt this kind scheme, fundamental purpose is in order to reduce the quality of strut members 3, avoid the larger modal vibration of mirror image pole generation in the wind tunnel test process, moreover strut members 3 is a body of revolution, utilizes common lathe to get final product processing and manufacturing, greatly reduces processing cost; By interference fit straight mouthful of pole 1 and strut members 3 positions, and locks with the connecting pin 2 of two right-angled intersection interference fit, and this connected mode has effectively guaranteed the integral rigidity of mirror image pole.
