A vibration reliability test method

Abstract

The invention discloses a vibration reliability testing method. By simulating the actual vibration state, the method obtains the mode shape, resonance frequency, stress-strain and deformation amplitude parameters of the designed product under corresponding vibration conditions. Analysis of characteristics provides a reliable basis for product structure improvement and performance improvement. The invention can simulate and verify the vibration reliability of the product at the design stage, which greatly facilitates the design of new anti-vibration structures and the introduction of new anti-vibration materials; improves the quality of product solutions at the design end, and solves the problem of repeated vibration in projects. However, there are problems of long period and high cost in sex test verification.

Description

technical field [0001] The invention relates to the technical field of vibration reliability testing, in particular to a vibration reliability testing method. Background technique [0002] For electronic equipment in the field environment, such as vehicle equipment including chassis, boards, etc., in order to meet the reliable use in long-term vibration environments, anti-vibration design is required at the beginning of the design, and then the design samples are reliably verified through vibration tests. After several adjustments and improvements, it can be finalized. The traditional method is for the designer to design the product based on experience, then complete the production of the sample, and then conduct the relevant vibration test on the prototype to identify the weak link of the sample, analyze the unreasonable structural design or the selection of the material, but the traditional test test every time The test cycle is very long, and multiple tests may be requir...

Problems solved by technology

The traditional method is for the designer to design the product based on experience, then complete the production of the sample, and then conduct the relevant vibration test on the prototype to identify the weak link of the sample, analyze the unreasonable structural design or the selection of the material, but the traditional test test every time The test cycle is very long, and multiple tests may be required until the final design is finalized, which greatly prolongs the research and development cycle and greatly increases the input cost
