Vibration Control Systems



An Introduction to Vibration Testing on Shakers
Vibration testing is essential to prevent catastrophic design failures for industries like automotive, aerospace, electronics, and military. Crystal Instruments provides precise and accurate shaker controllers to perform common tests such as Random, Sine, Shock and TWR. The fourth generation of vibration controllers is network based, infinitely scalable, and capable of very high channel count operations.


Random Testing with Vibration Controllers
Random Vibration Control provides precise multi-channel control in real time. The device under test is subjected to true random noise with a precisely shaped spectrum with either Gaussian or non-Gaussian amplitude statistics. With a control dynamic range up to 90 dB, up to 512 channels can be enabled for Control, Notching, Monitoring and time data recording.


Time Waveform Replication Testing
In addition to the three major test types of Sine, Random and Shock, Crystal Instruments also offers Time Waveform replication, or TWR. This is a method to exactly recreate, or replicate, a vibration in its time waveform format on a shaker system. The data is typically taken from a field environment. TWR allows engineers to accurately reproduce the data collected in the field.


Swept Sine Testing with Vibration Controllers
Sine tests are a popular method to simulate real-world vibration because most rotating machinery creates vibrations of a sinusoidal nature. When shakers vibrate according to a Sine profile, they reflect the types of vibrations often found in automobiles, airplanes, factories, and many types of pumps and engines. Crystal Instruments designed the fourth generation vibration controllers that uses the latest technology.


Shock Control by Crystal Instruments
Like other types of vibration tests, shock tests, are used to measure the reliability and durability of the object under test. Classical Shock Control provides precise, real-time, multi-channel control and analysis of a transient motion in the time domain. Classical pulse shapes include half-sine, haversine, terminal-peak sawtooth, initial-peak saw tooth, triangle, rectangle, and trapezoid.
