Selection Differences Between Random Vibration and Sine Vibration Tests
This article primarily discusses the differences between random vibration and sinusoidal vibration tests. Sinusoidal vibration uses a periodic signal at a single frequency, making it suitable for identifying resonance points and conducting fatigue tests. Random vibration, on the other hand, employs a broadband random signal to simulate real-world environments, such as transportation jolts, making it more appropriate for reliability acceptance testing.
The role of a bending stiffness tester in evaluating the rigidity and formability of cardboard.
The bending stiffness tester evaluates the rigidity and formability of cardboard by measuring its resistance to bending deformation. Based on the beam bending theory, it is tested under standard conditions, providing bending stiffness value as the core indicator.
For electromagnetic vibration tables, whether to choose sweep frequency or fixed frequency testing standards for simulating transportation is crucial; do not make a random selection if you are unsure.
The electromagnetic vibration table is used to simulate transportation vibrations and test the durability of products and packaging. There are two types of tests: fixed-frequency and sweep-frequency. The selection should be based on the test objectives and relevant standards to avoid arbitrary choices. For new products, it is recommended to first conduct a sweep-frequency test to identify resonance points, followed by fixed-frequency tests as needed.
