The invention discloses a throat expansion and retraction flexibility detection device used for an adjustable tail pipe. The throat expansion and retraction flexibility detection device used for the adjustable tail pipe comprises a base assembly, a left vertical plate assembly, a right vertical plate assembly, a sliding sleeve assembly, a push-pull disc assembly, a plurality of push-pull rod assemblies, a force sensor, a displacement sensor and a diffusion end limit assembly. Through reasonable designing and installing of all the assemblies, the effect that a synchronous ring serves as a drive part to drive a transmission mechanism of the adjustable tail pipe to drive a plurality of adjustment sheets of the adjustable tail pipe to move is finally achieved, and the stress and displacement amount of the synchronous ring are measured in the moving process of the synchronous ring. According to the embodiment of the throat expansion and retraction flexibility detection device used for the adjustable tail pipe, throat expansion and retraction flexibility of the adjustable tail pipe is detected, so that requirements for researching the throat expansion and retraction flexibility of the adjustable tail pipe in the process of researching the adjustable tail pipe are met.
Description
technical field [0001] The invention relates to the field of vehicles, in particular to a throat expansion and contraction flexibility detection device for an adjustable tail nozzle. Background technique [0002] In the development and production of the adjustable tail nozzle of the ramjet, it is necessary to test the throat expansion and contraction flexibility of the adjustable tail nozzle. Due to the complex structure of the adjustable tail nozzle, it is impossible to detect the throat expansion and contraction flexibility of the adjustable tail nozzle using the existing detection tools. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. Therefore, an object of the present invention is to provide a throat expansion and contraction flexibility detection device for an adjustable tail nozzle. [0004] In order to achieve the above purpose, an embodiment of the present inventio...
