Vibration may have an impact on the durability and reliability of machinery and structures and cause problems such as damage, deterioration, irregular shut-down, or accidents. Vibration testing constitutes an important countermeasure to prevent such problems.
In order to design and construct more reliable products, it is highly recommended that vibration and shock tests be incorporated into sample or finished product tests. To resolve vibration-related problems and improve product quality, it is recommended that vibration measurement (i.e. shock test) be performed for a sample or all parts of a mass-produced series.
Vibration tests simulate the vibration environment to which the product will be exposed during live operation. Products are tested using realistic environmental simulation to verify developments, identify durability, etc.
There are two types of vibration tests
“Vibration test”: This vibration test is used to inspect a sample or representative model of a mass production series. It is used to identify constructional defects in the product.
“Vibration exposure screening”: All products produced are tested to eliminate and reject defective parts and release good parts. This might be a mandatory process in certain industries.
