MIMO Shock Response Spectrum

Multiple-Input Multiple-Output SRS VCS

The Shock Response Spectrum vibration test control package provides controls to meet a target Required Response Spectrum (RRS). Waveforms are automatically synthesized from a user-specified SRS reference profile using sine wavelets. The Transient Control option allows control of imported transient files. Users can apply high frequency waveforms and alarm and abort tolerances to any active channel to provide an extra degree of safety for delicate test articles.

Multiple-Input Multiple-Output (MIMO) Shock Response Spectrum (SRS) Control

MIMO Shock Response Spectrum Features

  • Waveform Synthesis Methods: control time waveform is generated from damped sine or sine beat components
  • Damped Sine Parameters: frequency, amplitude, critical damping factor, delay
  • Sine Beat Parameters: frequency, amplitude, number of half sine delays
  • Component Generation: auto or manually controlled
  • Synthesis Parameters: waveform duration, max % of error, max number of iterations

Safety Features

  • Abort Sensitivity: a single parameter allows the ensitivity and tolerance of various safety checks to be asily adjusted between customizable lower and upper bounds
  • Shaker Safety Limits: limits for shaker acceleration, velocity, and displacement
  • Open Loop Detection: open loop detection for control signal and each input channel. Detection is based on maximum control loss or maximum RMS rate of change in the input channels.
  • Control Limits: enforces abort time limits for control signals. Allowable ratio of points exceeding abort limits to total number points in a frame: 0 – 100%
  • Max Drive Limit: maximum voltage limit for drive output
  • Time Domain Limit: Raw, or RMS to any input channel

Continuous Data Recording

During vibration control, all measurement input and drive signals can continuously record to a Spider-NAS or the internal storage residing in each front-end. Users can view and analyze data files with Crystal Instruments Post Analyzer. The variable sampling rate can be enabled to simultaneously record slow-change signals together with high speed vibration data.

Vibration Utilities App

Crystal Instruments in partnership with our sister shaker company Sentek Dynamics provides users with the Vibration Utilities mobile app on iOS and Android. This app provides calculation features for sizing your vibration profile (Random, Sine or Shock) and searches through our catalogue of shakers and controllers for the best fit.

Monitoring Through EDM Cloud

All vibration tests in EDM-VCS support status checks through EDM Cloud. With EDM Cloud support, users can set up any VCS test to upload live data or run logs for completed tests to a cloud storage space provided by Crystal Instruments, where data is securely stored in the user’s account.

The EDM Cloud website is located at https://cloud.go-ci.com. Users can access EDM Cloud from anywhere in the world to check the status of past and current tests. A secure login flow ensures the status can only be checked by authorized personnel with proper credentials. Multiple logins for accessing the same Cloud account is available.
