These sensors typically possess exceptional measurement resolution as the result of its comparatively larger size, which furnishes a stronger output signal and a lower noise floor. This fact means that in a world filled with energy and movement, vibrations or the oscillating responses of objects when moved from a position of rest are the norm. This can be correlated to the damage potential based on an input response. READ MORE CABLE VS. This category of cookies cannot be disabled. PCB’s high sensitivity ICP® accelerometers are specifically designed to enable the detection of ultra-low-level, low-frequency vibrations associated with very large structures, foundations, and earth tremors.

From sub-atomic particles all the way up to skyscrapers, internal movements and motions resulting from the absorption of energy make all objects vibrate to some degree. Vibration testing has just one linear degree of freedom. Applied Technical Services, Inc. now offers in-house seismic vibration testing in full compliance with the requirements of IEEE 344.In states where Applied Technical Services, Inc. does not provide engineering services, engineering services will be provided by ATS Engineering, (P)LLC or a licensed contractor.3 Independent Simultaneous Axes of Motion (X,Y,Z translation)Table Size of 36"x36" with Grid of 1/2" - 13 Tapped Holes on 4"x4" PatternFrequency Range of Operation 0-100 Hz with Ability to Operate Up to 150 Hz for Purposes of Resonance SearchesState of the Art PC-Based Digital Controller (Vibration Research) and 12 Channels of Piezoelectric AccelerometersIndependent High-Speed DAQ Systems for Chatter Monitoring (64 Channels)10CFR50 Appendix B Nuclear Quality Assurance Requirements10CFR21 Requirements for the Reporting of Non ConformancesISO/IEC 17025 Competence of Testing and Calibration Laboratories Run a shock pulse defined by a frequency vs. G peak table.Use a synthetic pulse OR a user defined time history waveform as the starting point, then VibrationVIEW will continue to modify the wavelets which adjusts the time history waveform to meet the SRS demand.Shock Response Spectrum is an accepted tool for developing laboratory shock tests.
ATS’ vibration testing services are administered to meet vibration qualification and safety compliance requirements. Earthquake testing involves excitation with a much bigger displacement (up to 300mm peak to peak).
The VR9500 is capable of running a user-defined time transient which is also used to run earthquake tests with the standard Bellcore earthquake time transients. "Vibration Stress Screening": All production products are tested to eliminate faulty units and approved good units. Kinectrics offers seismic testing, vibration testing and seismic qualification services for safety-related and telecommunications equipment in the nuclear industry. Users can run earthquake tests similar to the Bellcore standards along with any other earthquake time history.UDT allows for the creation of arbitrary periodic waveforms.

To move from the time domain to the frequency domain we have 2 possible solutionsThe FFT provides us the magnitude at various frequencies AND phase information at those frequencies. It also supports defining a test with enveloped data from multiple shock events.Time domain study of shock pulses is not sufficient. "Vibration Experiment": Vibration testing that is used to test a sample or representative model of volume production. UDT can better control short duration time history files, transient events, or very short road load data.VR’s vibration controller and vibration control software are comparable with any electrodynamic or servohydraulic shaker. Vibration Research Corporation’s VibrationVIEW software offers a chatter monitoring package that is capable of detecting and measuring chatter events.So whether you are involved in seismic vibration testing of a product containing relays or motor contactors, concerned about possible discontinuities in your relays, or need to evaluate the acceptance criteria for your relays (IEEE 501; ANSI C37.98), Vibration Research’s chatter monitoring capabilities will serve you well.Structures and equipment installed in data Centers located in seismically active regions must be designed to protect the operating equipment in the event of an earthquake.
