Vibration test software

controlsafetyEDM

The earthquake vibration testing package provides controls to meet a target a Required Response Spectrum (RRS). Waveforms are automatically synthesized from a user specified SRS reference profile using random type of wavelets, uniform or shaped. Alarm and abort tolerances may be applied to any active channel to provide an extra degree of safety for delicate test articles. Earthquake Testing Control Features Compliance: IEEE 344-2013 Waveform Synthesis Methods: damped sine, sine beat, uniform random, or shaped random Component Generation: auto or manually controlled Random Wavelet Definition: frequency, amplitude Shaped Random Time Window: user defined rising time, hold time and decay time Component Generation: auto or manually controlled Synthesis Parameters: waveform duration, max % of error, max number of iterations Full Envelope: configure test response spectrum to be greater than RRS in terms of dB To simulate equipment in a structure subject to earthquakes, vibration tests for seismic qualification utilizes different types of motion to effectively simulate the postulated seismic environment. Single frequency and multiple frequency are the two categories of motion that these types of motion fall into. Each category includes multiple waveform types for different cases. Single-frequency testing simulates the floor motion vibrating at the predominant frequency. It includes the following waveforms of motion, which can all be simulated by EDM VCS.
