Description
Technical field
The utility model relates to environmental mechanics testing equipment field, is specifically related to the connector structure of a kind of slender rod piece dual stage synchronous vibration test.
Background technology
Dynamic environmental test---vibration test, is mainly used to analog equipment at the environment used, load and unload and vibrated in transportation, to determine the adaptability of this product to various vibration.The integrity of a product structure can being evaluated by such vibration test, the rationality of serviceability index parameter, providing rational foundation for examining the quality of this product.Vibration test is generally used for the sophisticated products such as Aero-Space, also for auto parts and components and instrument and meter electronic product.
For the vibration test of slender rod piece, adopt dual stage due to the restriction of vibrated stage body table top and excited vibration test.In fact due to reasons such as stage body manufacture and controller control lags, be difficult to the synchronous vibration under the state of realizing ideal, general synchronous vibration test just simulates dual stage simultaneous test with the test that dual stage convergence is synchronous.In order to simulate dual stage simultaneous test, except adopt the controller of multi output in controller except, special coupling arrangement is adopted in the connection of stage body and slender rod piece, infringement when solving and avoid two stage bodies asynchronous, test specimen and test-bed body caused, guarantee that test is more realistic, more true to nature, and repetitive operation, carry out repeatedly comparison.
In prior art, shown in accompanying drawing 1, for long test specimen dual stage synchronous vibration test, usual method increases to join hingless connector, this hingless connector is composed of, one of them connector is rigid connecting joint 31, and rigid connecting joint 31 and vibration table 6 are connected by screw, and are connected between rigid connecting joint with long test specimen 5 by clamping element 7; Another connector is flexible connector 32, and flexible connector 32 and vibration table 6 are connected by screw, and are connected between flexible connector with long test specimen 5 by clamping element.When dual stage synchronous vibration is tested, geometrical interference when eliminating synchronous vibration by the elastic deformation of flexible connector 32.There is following defect in said structure: because the load-bearing capacity of flexible connector 32 and structural rigidity are conflicts, be difficult to the requirement meeting two aspects, vibrate the horizontal traction action power that stage body has a certain size on the length direction of long test specimen 5, have certain infringement to vibration stage body.
In prior art, shown in accompanying drawing 2, for long test specimen dual stage synchronous vibration test, a kind of method is also had to be increase to join a pair pair of Spherical hinge connector 41, as shown in Figure 2, this pair of Spherical hinge connector 41, has very high joint mobility, in limited corner, activity freely, solves the geometrical interference problem of dual stage synchronous vibration well.But, because two connectors are all two Spherical hinge connectors 41, so can any one party be swung in spherical angle, produce the defect that cannot uprightly stand firm.General user at the trial, draws extension with one or two elastic pulling force ropes 42 above long test specimen 5, reduces the annoying vibration arbitrarily swung, the vertical vibration of standard has superposed the component in other directions many, has reduced the verisimilitude of test; Sometimes must prop up the suspension shelf 43 taking elastic pulling force rope 42 temporarily, increase extra work amount.
