Abstract
The present invention belongs to the technical field of structural design, and relates to a tool used for single-axis vibration vector decomposition. The tool is characterized by comprising an equipment installation bottom surface and a vibration product working surface. Through adoption of the tool of the present invention, a single-axis vibration vector can be decomposed, and vibration test requirements of a product in three axis directions, i.e., X axis, Y axis and Z axis, can be satisfied at the same time, so that a vibrated object has quantitative vibration response respectively in the three axis directions, thereby overcoming the defect that single-axis vibration equipment can only achieve single-direction vibration response of a product at the same time, greatly shortening a vibration test period, and improving working efficiency.
Description
Technical field
The present invention's design belongs to structure-design technique field, relates to a kind of frock of decomposing for single shaft vibration vector.
Background technology
In the research and production process of electronic equipment, various defects can be introduced because of various reasons, for example: used defective components and parts, parts, enclosure, the misoperation of manufacture process, process stipulation imperfection, they bring impact all will to the reliability of product. Some defect can be got rid of by conventional measuring means (as range estimation, normal temperature, functional test), and some defect cannot check out with conventional means, be called as latent defect. If do not reject these potential defects before product is paid, come out the most during use. Therefore, we need to carry out environmental stress screening before product comes into operation, it is applied to vibration, make latent defect accelerated development become initial failure, reject the initial failure of components and parts, parts and the deficiency of exposure Design and manufacture technique, make the reliability of being sieved product more approach design level, thereby improve and ensure the reliability of product. For a long time, in the vibration-testing test of conditional electronic equipment, use single shaft vibratory equipment can only carry out at one time the vibration-testing of single axial, complete the environmental stress test of a set of product is needed respectively X, Y, tri-axles of Z on product to be tested. So not only expend a large amount of test periods, and reduced the utilization rate of resource.
Summary of the invention
The object of the invention is: for the deficiencies in the prior art, a kind of frock of decomposing for single shaft vibration vector has been proposed, by apply the design on single shaft vibratory equipment, by vibrational excitation resolution of vectors, while making vibration test, the product that shaken can respond X on product, Y, tri-axial excitation of Z simultaneously, shortens test period, raises the efficiency.
Technical scheme of the present invention is:
A kind of frock of decomposing for single shaft vibration vector, it is characterized in that: entirety adopts the stereochemical structure that is at least six faces, comprise equipment installation bottom surface (1) and vibration product work face (2), equipment is installed bottom surface (1) and is arranged on workbench for horizontal plane, vibration product work face (2) is space oblique placing surfaces, the equal out of plumb of x-axis, y-axis and z-axis that is with stage coordinates of vibration product work face (2) or parallel.
Further, equipment is installed bottom surface (1) and is provided with equipment fixing hole (3), vibration product work face (2) is provided with vibration product fixing hole (4), frock is arranged on workbench by equipment fixing hole (3), and vibration product is fixed on vibration product work face (2) by being provided with vibration product fixing hole (4).
In vibration test, by vibration product work face (2) angle and the setting angle adjustment of inertial navigation product on working face, accomplish integrated tooling to apply single shaft excitation, on product, obtain three axle response. Under single shaft excitation, the ratio that makes to be arranged on three the axial response accelerations of product on product work face approaches the setting value of oblique placing surfaces; By resolution of vectors, there is respectively vibratory response in product three axles that make to obtain to be shaken, reaches purpose of design.
Advantage of the present invention is: meeting under original vibration frequency and precision prerequisite, utilize the tilting supporting framework design of integral type, make only need to carry out vibration test by single shaft resolution of vectors and can meet in product vibration test needs to the axially demands of vibration respectively of tri-of X, Y on product, Z, shorten greatly test period, increased work efficiency.

Detailed description of the invention:
Below the present invention is described in further detail. Referring to figs. 1 through Fig. 3, a kind of frock of decomposing for single shaft vibration vector, it is characterized in that: entirety adopts the stereochemical structure that is at least six faces, comprise equipment installation bottom surface 1 and vibration product work face 2, equipment is installed bottom surface 1 and is arranged on workbench for horizontal plane, vibration product work face 2 is space oblique placing surfaces, the equal out of plumb of x-axis, y-axis and z-axis that is with stage coordinates of vibration product work face 2 or parallel.
Equipment is installed bottom surface 1 and is provided with equipment fixing hole 3, vibration product work face 2 is provided with vibration product fixing hole 4, this equipment is arranged on workbench by equipment fixing hole 3, and vibration product is fixed on vibration product work face 2 by being provided with vibration product fixing hole 4. There is certain space angle with the normal vector of workbench in vibration product work face 2, excitation is decomposed along X-axis, Y-axis and the Z-direction of vibration product work face 2, obtains required oscillating component. By inclined-plane, space, accomplish integral device to apply single shaft excitation, on product, obtain three axle response. Integral device adopts the tilting supporting framework of integral type, and three the axial vibrational excitations that all can obtain of product that ensure to be shaken respond.
Embodiment 1:
Utilize this frock to select product to test, establish mikey vector and beIts projected size at X axis isThis vector and X-axis angle areProjected size in Y-axis isThis vector and Y-axis angle areProjected size in Z-axis direction isThis vector and Z axis angle are
Requiring test products is X:Y:Z=1:0.71:1.12 at the ratio of the vibratory response of X, Y, tri-directions of Z. The angle that therefore, can draw single shaft vibration vector and product three axles is respectively By this frock actual vibration test, record three axle response than being X:Y:Z=1:0.9:1.13, thus, this frock can ensure measuring accuracy, meets single shaft excitation, the testing requirement of three axle response.
