Classical Shock
The ability to use your
electro-dynamic or electro-hydraulic shaker table to produce
classical shape pulses with JAGUAR greatly enhances your
laboratory ’s productivity.
There is no need to rely upon drop shock tables to reproduce
specific acceleration shapes and velocities to evaluate your
product. The inherent setup problems and time consuming snubber
changes can be set aside. Let JAGUAR ’s adaptive control
scheme quickly compensate for loop anomalies, including
amplitude non-linearity, correct instrumentation DC inaccuracies
with its built-in trend removal capability and end up with a
repeatable test and a comprehensive analysis solution that is
completed the instant your shaker pulse has concluded.
The arbitrary waveform feature allows performance beyond
anything that could be achieved with dedicated shock table
products. Used in conjunction with JAGUAR ’s Waveform
Processor, you may import digital files containing measured
acceleration from real world applications.
Those data may then be re-sampled, edited or filtered. Then you
may utilize the resultant waveform in closed-loop, compensated
shaker replication in the laboratory to achieve repeatable
simulations of real world events scaled and modified, as you
need, for your requirements.
Premium Hardware Makes the Difference Accuracy in testing
begins with the hardware. High quality linear phase filters,
guaranteed alias protection, and extremely high dynamic range
Sigma/Delta Converters, extremely high fidelity signal
generation are all required for making a good shock tester.
JAGUAR is the best. This is critical due to the transient nature
of the data. All decisions and understanding of structural
response originate from one time record, generated by one pulse.
JAGUAR filters differ from design perfection by less than +/-1
degree across the entire frequency range of 0 to 20 kHz.
Channel-to- channel phase matching differs by no more than +/-2
degrees across the same frequency range. The result is
extraordinary accuracy. The filter design is optimized for
transient operations so that the inherent ringing characteristic
of all filters is absent in the operating range for all response
data for mechanical systems. This means your data are NOT
altered by a filter oscillation that alternately adds and
subtracts energy from the actual measurement, before you see it.
This means the data you analyze with JAGUAR Shock are accurate.
Control Quality Unparalleled Rapid equalization of the
external system to produce an accurate response waveform means
you will expose your device under test to only the levels and
duration of energy required –no unnecessary damage
accumulation.
Choice of:
 | Pre-pulse Compensation
| Post-pulse Compensation
| |
Pre-and Post-pulse Compensation
lets you decide how best to ensure zero displacement and zero
velocity at the conclusion of the pulse.
Optimization of the pulse for your shaker ay be accomplished
with :
| Bipolar optimization
–automatically assures minimum displacement
| Symmetrical optimization
| Asymmetrical optimization
– permits full travel of the armature for longer
stroke

Securing hundreds of time waveforms from a single Shock test is
one of many reasons JAGUAR is the most powerful and capable
Shock system in the world. JAGUAR unleashes this power by
permitting the user instant review of all the data, including:
