Embodiment 1

[0016] Use this tooling to select products for testing, let the space unit vector be Then its projection size on the X axis is The angle between this vector and the X-axis is The projection size on the Y axis is The angle between this vector and the Y axis is The projection size on the Z axis is The angle between this vector and the Z axis is

[0017] The ratio of the vibration response of the test product in the three directions of X, Y, and Z is required to be X:Y:Z=1:0.71:1.12. Therefore, it can be concluded that the angles between the uniaxial vibration vector and the three axes of the product are respectively Through the actual vibration test of the tool, the measured three-axis response ratio is X:Y:Z=1:0.9:1.13. Therefore, the tool can guarantee the test accuracy and meet the test requirements of single-axis excitation and three-axis response.

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 [0001] The design of the invention belongs to the technical field of structural design, and relates to a tool for uniaxial vibration vector decomposition. Background technique [0002] In the development and production process of electronic equipment, various defects will be introduced due to various reasons, such as: the use of defective components, parts, outsourcing parts, improper operation of the manufacturing process, and imperfect process regulations. It will affect the reliability of the product. Some defects can be eliminated by conventional inspection methods (such as visual inspection, normal temperature, functional test), while some defects cannot be detected by conventional methods, which are called latent defects. If these potential defects are not removed before the product is delivered, it will eventually be exposed during use. Therefore, we need to carry out environmental stress screening before the product is put into use, apply vibration ...
