Define the test duration at each output level. Enter up to 200 separate levels and loop to repeat sequences without interruption.
Access standard classical shock pulses and vary pre/post-pulse compensation amplitude and shape.
Alternatively, select the user-defined transient option to build a pulse from a recorded waveform.
Import a time-history file to form a pulse shape from a recorded transient. Supports up to about 65,000 samples.
Fulfill requirements from test standards such as MIL-STD-810, DO-160, ISTA, ASTM, SAE, and IEC 60068. Select the tolerances defined by the test standard.
Shock testing is often required in industries such as:
Available graph display options include acceleration, velocity, displacement, output voltage, acceleration, and drive spectrum.
Graphs can be easily auto-scaled, and the cursor display can be adjusted. Data and text annotations can be easily placed on the graphs, and data values update live with changes.
A vibration test may call for a user-defined transient pulse or a shock response spectrum (SRS) for more complex shock events. VibrationVIEW features software packages for generating more complex shock testing, including the Shock Response Spectrum (VR9302) and Transient Waveforms Control (VR9301) software add-ons.
There is also software designed for IEEE-344 standards, chatter monitoring, and other advanced analyzer functions. These transient events are difficult to characterize and analyze with basic tools.
A shock test is employed to test a system’s capability to survive a drop, hit, impact, fall, explosion, or any other source of transient vibration that may occur in the real world. Many vibration test standards define classical shock pulses. However, more advanced shock testing may require a complex transient pulse that cannot be replicated by a classical shock.
Classical shock pulses are a simple method of generating a shock pulse. They generate a reliable and straightforward response that engineers can use for product evaluation and durability testing.
However, a vibration test may require a user-defined transient pulse or a shock response spectrum (SRS) to replicate more complex shock events. There are specialized software packages designed to recreate these complex pulses, including the Shock Response Spectrum software.
Complex shock pulses better represent real-world conditions. Many synthetic pulses can represent a complex transient waveform and have a frequency response comparable to the operational environment. It is also possible to replicate a recorded signal from the real world and process the signal using an iterative shock control loop to effectively generate and control the complex waveform.
Perform drop shock testing with the intuitive Shock software. Many products will experience shock vibrations during shipping and handling or in use. Engineers use drop shock testing to simulate these conditions in the lab and confirm the structural integrity of the device.
