Abstract
The utility model discloses an airway structure applied to vibration test equipment. The airway structure comprises an airflow supply duct communicated with a compressed gas supply device, and an airflow jetting duct used for fitting the airflow supply duct and independent of the airflow supply duct, wherein the diameter of an airflow input end of the airflow jetting duct is greater than the diameter of an airflow output end of the airflow jetting duct and the diameter of the airflow supply duct. The airflow jetting duct preferably adopts a tapered through hole. More preferably, the airflow jetting duct has a smooth inner wall surface. By the aid of the design of the utility model, compressed airflow can be effectively prevented from being dissipated at the interface of the airflow supply duct and the airflow jetting duct, the utilization rate of compressed airflow is improved, the influence of dissipated airflow on the stability of a system structure is avoided, and the stability of airflow jetted out from the airflow jetting duct can be effectively improved.
Description
Technical field
The utility model relates to a kind of vibration rig, and particularly a kind of air passage structure that is applied to vibration test equipment, belongs to vibration test technical field.
Background technology
For the blade class device in the equipment such as engine, before application, generally need to carry out vibration-testing to it, to find out the stability of its structure.At present, normally utilize electric vibration table to test blade, but be limited to the restriction of electric vibration table proper property, in this type of vibration-testing process, often be difficult to the actual working environment of the simulation blade of high emulation, and its test frequency range is easily confined to lower frequency ranges mostly, and then make the vibration-testing data and the actual conditions that obtain have very large error.
For this reason, this case utility model people has proposed the high on-line vibration pilot system of a kind of blade, consult Fig. 1-Fig. 2, it comprises frame 5, at least one compressed air stream feedway 2 and a rotating disk 1 that can rotate around self axis, wherein, in rotating disk card, around its center, be provided with ringwise plural jet-impingement duct 11 '.By rotating shaft 4, order about described rotating disk according to setting speed rotation, and make this plural number through hole successively from least one compressed air stream feedway front process, thereby make can intermittently see through described rotating disk and impact tested blade 3 with pulse mode by the compressed air stream of this at least one compressed air stream feedway output.System by this, the actual working environment of the simulation blade of the high emulation of energy, more than test frequency can reach 6000Hz.
But, this case utility model people finds in a large amount of practices, when adopting air passage structure shown in Fig. 3, compressed air stream very easily dissipates in air-flow supply duct and 11 ' interface, jet-impingement duct, cause compressed air stream utilization factor lower, and the air-flow dissipating also can impact compressed air stream feedway and rotating disk, then affects the accuracy of stability and the test result of system architecture.
Utility model content
Fundamental purpose of the present utility model is to provide a kind of air passage structure that is applied to vibration test equipment, to overcome deficiency of the prior art.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme:
An air passage structure that is applied to vibration test equipment, comprising:
The air-flow being communicated with pressure gas feedway is supplied with duct,
And, in order to supply with duct with described air-flow, coordinates, but be independent of the jet-impingement duct in described air-flow supply duct;
Wherein, the bore of the air flow inlet end in described jet-impingement duct is greater than the bore of its air-flow output terminal and the bore in described air-flow supply duct.
As one of comparatively preferred embodiment, described jet-impingement duct adopts conical through-hole.
Particularly preferred, described jet-impingement duct has smooth inner wall face.
Further, while coordinating with described jet-impingement duct in described air-flow supply duct, both coaxially arrange for this.
Further, at the breech face in described air-flow supply duct, approach but do not contact with the air flow inlet end face in described jet-impingement duct.
Pass through previous designs, make the utility model compared with prior art at least tool have the following advantages: can effectively prevent that compressed air stream from supplying with the dissipation of duct and interface, jet-impingement duct at air-flow, improve compressed air stream utilization factor, and avoid the impact of air-flow on system architecture because dissipating, especially by employing, there is the taper hole type jet-impingement duct of smooth inner wall face, also can effectively improve the airflow stability ejecting from jet-impingement duct.
