Packaging testing vibration test method

Haida Xiaobian introduces vibration testing for the most common test methods in packaging testing. The following are the details:

5.2. Vibration Test

5.2.1. What to Do for Vibration Testing

5.1.1. During the transportation process, the main factor that causes the vibration to damage the product is the length of time. Even if the vibration intensity in the truck is very low, it is often lower than the value = "1" unitname = "g"> 1G, but sustainable a long time.

Nth="12" year="1899">5.2.1 In the United States, 2500 miles (4,000 kilometers) of cargo between the coasts has been in transit for at least 50 hours. Such a long period of vibration can cause parts to wear out, become loose, and gradually become loose. The damage to the product.

Then on the earthquake 7100/200=35.5 minutes

If possible, turn the package sample 90 degrees

If the package sample is too large, rotate the package sample 180 degrees

★ Gradually increase the speed until the metal ruler (2′′x4′′x0.06) intermittently passes between the surface of the platform and the longest side of the bottom of the packaged product.

★ Set vibration time

When the time is halfway, stop shaking

If possible, turn the package sample 90 degrees

If the package sample is too large, rotate the package sample 180 degrees

Slowly increase the speed until the metal ruler (2′′x4′′x0.06) intermittently passes between the surface of the platform and the longest side of the bottom of the packaged product.
