Vibration test

Detail Information
Product Description

Vibration test
Project Introduction
Vibration testing is a laboratory artificial simulation of the effects of various vibration environments encountered by products (general electrical and electronic products) during storage, transportation, installation and use. It is used to evaluate whether the product can withstand various environmental vibrations. Whether it can be used normally without malfunction.
Testing purposes
Vibration testing can analyze and evaluate the reliability of the product before it officially leaves the factory, reduce the probability of defective products later, and also determine the requirements for product design and functionality.
Application scope
There is a lot of demand for vibration testing of electrical and electronic products, because most electronic products are precision products, such as mobile phones, tablets, etc. The internal structures and devices are relatively precise, and the vibration environment has a greater impact on them. It is necessary to ensure that the impact of vibration factors on product reliability is Influence.
Vibration test classification
Reliability vibration testing is generally divided into two types, sinusoidal vibration testing and random vibration testing. Sine vibration is a test method often used in laboratories to simulate vibrations caused by rotation, pulsation, and oscillation (occurring on ships, aircraft, vehicles, and space vehicles), as well as product structure resonance frequency analysis and resonance point residence verification. Mainly, it is divided into two types: sweep frequency vibration and fixed frequency vibration. The severity depends on the frequency range, amplitude value and test duration. Random vibration is used to simulate the seismic strength evaluation of the overall structure of the product and the transportation environment in the packaged state. The severity depends on the frequency range, GRMS, test duration and axial direction.

1. Sine vibration test: This test applies sine vibration to the test piece, which can be a sine fixed frequency or a sine sweep frequency vibration test.

2. Random vibration test: This test applies random vibration to the test piece. According to the frequency width of the random vibration, it is divided into broadband random vibration test and narrowband random vibration test.

method standards
Sinusoidal vibration: GB/T 2423.10 IEC 60068-2-6 EN 60068-2-6 ISO 8318 GB/T 4857.10 ISO 2247 GB/T 4857.7

Random vibration: GB/T 2423.56 IEC 60068-2-64

Test parameters
Vibration table parameters: maximum thrust, maximum acceleration, maximum speed, maximum displacement, vibration table size and weight, table resonance frequency, vibration table frequency range.

Sample parameters: sample size, sample weight, test parameters.
