The platform takes a three-freedom degree parallel robot mechanism as a primary form. The present invention is characterized in that a servo motor (2) and a guide rod (4) are arranged on a base (1), and a ball screw is connected with the servo motor (2). A screw nut is connected with a sliding block (5). A ball pivot on one end of a rigid support column (6) is connected with the sliding block (5), and a ball pivot on the other end of the rigid support column (6) is connected with a vibrating platform (7). The experimental platform drives the ball screw by the cycle period of three servo motors to realize the vibration of the vibrating platform in any direction in the space. The present invention has the advantages of low non-linearity of system vibration, simple control algorithm, convenient processing and assembling, good manufacturability, etc. and is applied to the laboratory for doing the vibrating environmental test with three freedom degrees. The present invention is an experimental device for testing the vibration proof strength and vibration proof stability for electromechanical products and components or simulating different vibrating environment.

Background technology
Anti-intensity and the anti-stability of shaking of shaking for test products has adopted various vibration test platforms.The Three Degree Of Freedom vibration environmental test platform that R and D are novel can make the anti-test of shaking of electronic product more approach actual conditions.
Parallel robot is the robot of a class brand new, its end piece can place near on the support or the support topology layout by a plurality of kinematic chains supportings of parallel connection and All Drives simultaneously, make it have many particular performances, parallel robot has all obtained using widely in fields such as machining, bionical, military, medical, biological, aerospace and oceanographic engineerings.Parallel robot has overcome the little shortcoming of parallel institution self work space as multi-freedom-degree vibration environmental test platform, has given full play to again that its kinematic chain is short, symmetry good, rigidity is big and the advantage of compact conformation.
Summary of the invention
Outstanding advantages such as the present invention proposes a kind of Three Degree Of Freedom vibration environmental test platform new architecture with rational deployment pattern, and the nonlinearity that this novel test platform has system vibration is low, dynamic perfromance good, control algolithm is simple, processing and assembling is good.Being applicable to and doing the Three Degree Of Freedom vibration environment test in the laboratory, is that electronic product, element are carried out anti-intensity and the anti-testing equipment that shakes stability test or simulate other vibration environment of shaking.
The technical solution adopted for the present invention to solve the technical problems is: test platform is an original shape with a kind of three-freedom parallel robot mechanism with rational deployment pattern, form by rigid support 6, the shaking table 7 of ball pivot by 1 three servomotors of pedestal 2, three ball guide screw nats 3, the three pairs of guide poles 4, the three pairs of slide blocks 5, three pairs of two ends generations, wherein, servomotor and guide pole are installed on the pedestal, ball-screw links to each other with servomotor, and nut links to each other with slide block; Rigid support one end ball pivot links to each other with slide block, and other end ball pivot links to each other with shaking table; The center of the three pair ball pivots with shaking table linking to each other corresponding with the three pairs of rigid supports is distributed in respectively on three mutually perpendicular surfaces on the shaking table, translation motion is only done at the center of three pairs of ball pivots that link to each other with slide block, and three pairs of guide pole axis are orthogonal in twos in the space.This test platform drives ball-screw by three servomotor cycles, can realize the vibration of shaking table at the space any direction.
The invention has the beneficial effects as follows: advantages such as the nonlinearity that this invention has system vibration is low, control algolithm simple, processing and assembling is good.Be applicable to and do the Three Degree Of Freedom vibration environment test in the laboratory that this invention makes shake intensity and the anti-stability test of shaking of electronic product, element anti-more approached actual conditions.
