The Lynx™ Shock Module solution generates different types of shock pulses to simulate the test item experiences in its real environment. As an expert in the field, Spectral Dynamics developed algorithms for shock testing with transfer function updating and coherence smoothing to accurately and quickly compensate for non-linearity or time varying changes which may occur with a dynamic load. The control strategy is easily defined by the user with pulse compensation, tolerances, number of control channels. SRS testing, automation of the shock test and repetitive pulse mode are available with our solution. The Lynx™ stands alone in the industry as the “true tool” in realistic shock environment simulation.

Classical Shock

Shock employs a patented adaptive equalization technique. Not a “Once per test”, amplitude only correction, Shockbut “adapts amplitude and phase” on every shock pulse to correct for non-linear conditions on both hydraulic and electrodynamic exciters.

Features:

• Pulse Types: Half-sine, sawtooth, trapezoidal, rectangular, and imported waveforms
• Belcore VERTQII seismic waveform
• Output frames up to 16,384 samples
• SRS analysis to 10 kHz on all active measurement channels
• SRS calculation (Maxi-Max, Primary+, Primary-, Residual+, Residual-)
• Manual or automatic operation with level scheduling
• Sophisticated drive compensation management to decrease equalization time for repetitive tests
• Direct Office links with PDF creation permits fast report generation
• The ability to employ true random energy for FRF Calculations provides excellent system identification.
• Provides the ability to use pulse, broadband random, or band limited random for the best system identification and accuracy.

Shock Synthesis

SRS Synthesis provides a robust capability to generate a nearly unlimited number of waveforms that will match your specified SRS. Transients may be manually or automatically generated from either damped sine or wavelet components with user specified optimization. Adaptive Control allows Lynx™ to learn your structure and rapidly resolve its unique dynamic characteristics (including phase changes during the test), producing very accurate tests. Exceptionally powerful Digital Signal Processing permits many parallel computations so all channels and resultant data may be viewed instantly and simultaneously.

Features:

• SRS analysis capability from 1/1 octave to 1/24 octave
• Automatic wavelet synthesis and convergence from SRS reference
• Optimization for time, displacement or acceleration
• Extensive wavelet editing capabilities
• Patented adaptive control technique for control of non-linear dynamics, not “Once per Test System ID”
• Sophisticated drive compensation management to decrease equalization time for repetitive tests
• Direct “Office” Reporting with PDF/Microsoft Word creation
