Description
Technical field
The invention belongs to high-speed rocket sledge sled test technical field, be specifically related to a kind of vibration damping slide block device for the test of high-speed rocket sledge.
Background technology
Rocket sledge sled test is the one very effective ground dynamic test between testing laboratory and full-scale flight test, this test method possesses full-scale dynamic test ability with it, testpieces quality and size are restricted hardly, test speed and overload level are greatly with efficient, safety, repeatable high, the excellent feature of economy, become the new theory identifying various weaponry, new technology, new material and the requisite testing equipment of new construction, aviation, space flight, weapons, electronics, the specialty such as nuclear weapon more and more brings rocket sled track test into fundamental test means in.
Slide block is the key member of rocket sledge, rocket sledge runs along rail high speed by means of the slide block be fastened on slide rail rail head, slide block should fasten track, rocket sledge is made to have the movement locus determined, do not depart from slide rail, keep certain interval again and between the rail head of track, slide block is passed through smoothly.This fastening structure just, makes slide block can by load such as suffered huge aerodynamic force, motor power, damping force during rocket sledge high-speed cruising, and the shock and vibration produced due to these load instability is delivered on slide rail; Simultaneously also can by can not be definitely smooth-going due to slide rail, when causing high-speed cruising, because the random shock that contacts, rub and collide and produce and vibration passing are to rocket sledge between slide block with track.Therefore slide block not only serves the effect of transmitted load between slide rail and rocket sledge, self also needs to have the good rigidity of structure and intensity simultaneously.Traditional slide block is generally designed to have stronger rigid structure, and slide block is connected with car body also to adopt and is rigidly connected.
But along with weaponry is to development that is high-speed, high-power and high-level efficiency direction, the impact of mechanical vibration on the quality of product, performance and the market competitiveness is increasing.The Design and manufacture of product plays conclusive effect to its dynamic property, product also needs on-line monitoring, the at any time Dynamic controlling such as tracing trouble and on-call maintenance when using, this just requires the test environment that Rocket sled test can provide the tests such as similar guided missile suitable, accelerating curve can be designed to approach the overload curves in practical flight as far as possible, and vibration environment is substantially close to the magnitude of practical flight in test.
The dynamic load that slide block and rail interaction produce, sharply increases along with the raising of Rocket sled test speed, on traditional testpieces that this forced vibration can be directly delivered to and rocket sledge carries of being rigidly connected.Therefore, under Rocket sled test environment, usual the born dynamic load of flight test exemplar may than more severe under free flight mode of operation.For high-speed test (HST), because the magnitude of vibration is excessive, be often difficult to meet the requirement of testpieces to vibration environment.Therefore, pursue simply slide block stiffness this for time design viewpoint very of a specified duration need to be reconsidered.
The many employings of traditional vibration reducing measure are requiring the mode of higher testpieces or core component junction mounting dampers wherein to vibration environment, when testpieces size and weight are comparatively large, be often difficult to realize when the installing space around core component is not enough.Simultaneously in order to the integrality of warranty test part, vibration damper is often arranged on its outside, the construction weight of rocket sledge and physical dimension are increased more, the thrust of rocket sledge engine and aerodynamic configuration are had higher requirement, causes the significantly raising of design difficulty and implementation cost.
