Testing w/ Vibration Controller to meet Standards
and reporting on past and present results as well as setting up new tests without disrupting test control performance. This controller is therefore ideal for a networked system. The Gigabit Ethernet card provides significantly reduced cabling costs and greater flexibility for installations requiring a remote shaker location. There is no reduction in control or acquisition speed with this architecture and the added benefit of PC data security in the safe environment of the control room. VibRunner... (read more)

Brake Rattle: Vibration and Noise Testing
It is noted that sine dwell tests are a good starting point given the ease of implementation without the need for advanced shaker controllers .
Optical payload isolation using the Miniature Vibration Isolation System (MVIS-II)
Sine dwell inputs at several tones between 5-100 Hz were commanded to the shaker in order to test the active controller performance.
Development of a Closed-Loop High-Cycle Resonant Fatigue Testing System
For the closed-loop HCF testing, Data- Physics SignalStar Vector® (called as DP Vector software in the followings) is used as shaker controller . The resonance search and dwell test option in DP Vector software is designed to perform vibration-based … To track resonant frequencies, a sine sweep test needs to be undertaken prior to the dwell test …
ENHANCEMENT OF MODAL SWEPT SINE DATA BY CONTROL OF EXCITING FORCES
A mode is tuned in with a sine dwell . The shaker output force is turned up to a desired maximum value. The con- troller is told to make a certain number of measurements over a specified decreasing force range.
Automotive vibration testing
Endurance dwell testing at resonance. For example an electronic controlboard mounted to a shaker tablc can be excited by means of a sine wave sweeping through a nominal fiequency range. The use of a stroboscope synchronised with the vibration controller enables the engineer to observe any bending …
