Abstract
The invention discloses a kind of elastic sheet vibration test system and method, described elastic sheet is the shell parts with circular section, and larger one end of described shell parts is openend.This test macro comprises: vibration generating arrangement; And, for by the circumference of described elastic sheet openend and described vibration generating arrangement around fixing rigidly connected fixed mechanism.This method of testing comprises: by the circumference of described elastic sheet openend and a vibration generating arrangement around being fixedly rigidly connected; And Vibration on Start-up generating means, carries out vibration-testing.Elastic sheet vibration test system structure of the present invention is simple, is easy to operation, and under height really simulates the condition of elastic sheet actual working state, can carries out vibration-testing to it, and test result is accurate, and can not cause damage to test specimen structure.
Description
Technical field
The present invention relates to a kind of envlronmental vibration test Apparatus and method for, particularly relate to a kind of vibration-testing apparatus and method of elastic sheet, belong to vibration test technical field.
Background technology
Among the assemblies such as the current fuel tank at space flight devices such as satellites, usually can arrange elastic sheet, this kind of elastic sheet is generally the semisphere shell parts be made up of the material with elasticity and good complex performance.In fuel tank, example is applied as with it, consult Fig. 1 a, when not injecting fuel in fuel tank, elastic sheet system and fuel tank upper inside wall are fitted substantially, and when fuel tank filled with fuel, then consulting Fig. 1 b, under the extruding of fuel, can there is deformation and substantially fit with fuel tank lower inner wall in elastic sheet; If the fuel in fuel tank starts to export, then springform sector-meeting state shown in complex to recovery Fig. 1 a gradually, and the fuel in fuel tank is extruded substantially completely, realize making full use of fuel.For ensureing that elastic sheet can have well stable performance, generally need before using to carry out vibration-testing to it, generally the local edge of elastic sheet openend is clamped on shaking table to carry out vibration test (consulting Fig. 2) at present, but this mode has shortcomings, such as: be not substantially inconsistent with practical situations, resonant frequency is on the low side, and then obtains untrue conclusion; And elastic sheet local pressure is excessive, test specimen may be caused to damage.
Summary of the invention
