Purpose of vibration testing of products Why do we have to do a vibration test on the product? The current world economic trend has moved from a regional economic model to a global economic trade. Whether it is a regional market or entering the global market, high-quality performance is not to be arrogant. And vibration testing can help your products leap into the high quality ranks.

1. Any product that is transported, used, stored, will produce collision vibrations, causing the product to be defective for a certain period of time.
2. Many products are used, because of the habits, many products are bad at this time or even just beyond the warranty period or because the value is not high or because the service is a bit difficult to find, the product has bad criticism of the brand, how many manufacturers know?
3. Really able to design production quality can help the product to be expected to see the shortcomings of the display and then improve. such as:
a) The design is that it can analyze the broken points and the bad points. b) When the quality is analyzed, the different easy-to-defect points generated by each batch of flash can be analyzed. c) During production, the vibration can be measured while vibrating, and the product defect rate is earlier. Discover d) Durable measurement, make the product durable, and make the components that are not durable improve early, the company brand reputation will be better. Dongguan Gaotian Testing Equipment Co., Ltd.
The product reaches the user's hand, and vibrations of different states will occur during this process, resulting in different degrees of damage to the product. Any damage to the product is not what the manufacturer and the customer would like to see. However, the vibration generated during the transportation process is difficult to avoid. If the packaging cost is increased, it will bring serious and unnecessary waste, and vice versa. Packaging has caused high cost of products and lost product image and market. These are not what we would like to see.
The vibration test began to sprout about 40 or 50 years ago. When the theory was established, it did not help people to remember its importance. Until the Second World War, many aircraft, ships, vehicles and equipment were accidentally discovered after use. The proportion of mechanical failures is quite high. According to the research results, most of the components are loose, cracked, and caused by the long-term resonance caused by their own structures or the carrying materials. Failure even caused huge losses. When this result was announced, the vibration test received attention from all walks of life, and they invested a lot of money and manpower to study. After the establishment of the modern theory of vibration measurement analysis and simulation analysis, the method and logic of vibration testing are continuously improved. In particular, the circulation of goods today is frequent, making vibration testing even more important. The purpose of the vibration test of Dongguan Gaotian Testing Equipment Co., Ltd. is to conduct a series of controllable vibration simulations in the test to test whether the product can withstand the test of transportation or vibration environment during the life cycle, and also determine the product design and function. Requirements standard. According to statistics, an increase of 3% in design levels will increase recycling by 20% and reduce unnecessary expenses by 18%. Vibration simulation has different methods according to different purposes, such as resonance search, resonance dwell, cyclic scan, random vibration and stress screening. The vibration effect meter includes: 1. The strength of the structure 2. The looseness of the combination Protect the wear of the material. Fourth, the damage of components. 5. Poor contact with electronic components. Sixth, the circuit is short-circuited and intermittently unstable. 7. The standard value offset of each piece. Eight, the bad parts screened out early. Nine, find the resonance relationship between parts, structure, packaging and transportation process, and improve its resonance factor. The vibration test procedure must evaluate the test specifications, the authenticity of the fixture design, the functional inspection during the test, and the evaluation, review and recommendations of the test specimens after the Zui.
The requirements of the vibration test are to confirm the reliability of the product and to screen out the defective products before leaving the factory, and evaluate the failure analysis of the defective products in order to become a high-level, high-reliability product.
