There is some confusion about the various tests available to the vibration testing engineer. Difficulties encountered usually center on the differences between sinusoidal vibration (sine testing) and random vibration testing. Strike a tuning fork and the sound you hear is the result of a single ...
3. Types of Vibration Control The most common types of vibration reproduced by a shaker system is sine, random, and shock. In fact some believe random control testing and sine control testing make up over 70% of all the environmental simulation testing. 3.1 Random Control Direct YouTube link...
Vibration analysis—a component of condition monitoring systems—utilizes vibration sensors to measure frequencies in an asset and detect abnormalities that may indicate a problem. At its core, vibration analysis is the study of the oscillatory motions of machines and their components around an establish...

ALT testing is also a very useful way to determine the effectiveness of derating. Derating is the process of reducing the load (typically voltage or current) on a component below its “rated” load, or equivlently selecting a component that is rated above the design load. How much the comp...
Calibration is configuring and verifying a measuring instrument's accuracy to ensure its readings match a known standard.
MTBF is often used in the design and testing phase to help ensure that components meet reliability requirements. Manufacturing MTBF is used in manufacturing to measure the reliability of pieces of equipment. By performing the MTBF calculation on machines, manufacturers can identify potential issues and...
The complete guide to signal conditioning in data acquisition. Learn what signal conditioning is, types of signal conditioners, and the technology behind.
with a consequential increase in both non-destructive testing (NDT) and manual inspection that is expensive and disruptive to efficient rolling stock maintenance. TWI plays a key role in an InnovateUK project, aiming to use complimentary methods of high frequency vibration and Acoustic Emission (AE...
Since random testing excites all of a structure's resonant frequencies simultaneously, it is well suited to vibration qualification testing, and characterising a structure’s dynamics. bksv.com 由于随机测试可同时激起结 构的所有共振频率,因此非常适合振动鉴定测试,以及表征结构的动态特征。 bksv.cn...
