Designation

of vibration testing control system ZET 024

Shaker controller (VCS) ZET 024 is a software and hardware suite based on multi-channel data acquisition system used for receiving, amplification and conversion of the analog signal received from the vibration transducers (the transducers are not included into delivery scope), power supply of the shaker power amplifier, recording of the current parameters of the testing process and adjustment of the control signal via the feedback system. The system conducts spectral analysis with the use of FFT and IIR.

Task-specific ZETLAB software is used for control of ZET 024 operation modes and recording of the measurement parameters. Information of the vibration parameters is displayed at the external devices in user-friendly format. ZETLAB Software allows to solve a variety of tasks related to the vibration testing control (e.g., selection of the reference transducer based on the analysis of statistical characteristics), thus, considerably simplifying the work process for an operator.

Shaker controller (VCS) ZET 024 is used together with vibration testing systems for control of the testing process in the following basic modes:

  • sinusoidal vibration with constant frequency or frequency sweep (Sine)
  • resonance search, track and dwell (RSTD)
  • broad-band random vibration with controlled shape of the spectrum (Random)
  • classical shock (Shock)
  • gunfire impact imitation
  • synthesized pulse with a set shock response spectrum (SRS)
  • transient time history (TTH)
  • field data replication mode (FDR)
  • fatigue damage spectrum (FDS)
  • kurtosis control (Kurtosion)

The system also supports operation in the combined loads mode:

  • Sine-on-Random
  • Random-on-Random
  • Sine-on-Sine
  • Sine-and-Random-on-Random

The systems of ZET 02X series can be used together with shaker systems for primary certification and periodical verification, as well as for a variety of additional testing types in compliance with the applicable technical requirements.
