In general, all of Roehrig Engineering’s software is developed in house by us with input from our customers.  Our software platforms had their start over 25 years ago and continue to evolve based on requirements of the testing equipment and the need of the end user.  Windows based and mouse driven, it has won over the harshest critics and leant itself to first time computer users the world over.

SHOCK 6: Damper Development and Performance Testing

All Roehrig Engineering damper dynamometers use Shock 6 Test & Control Software to develop tests, execute them and collect the resulting data.  Various versions of Shock have been developed with customer driven features and requests over the last 20 years.  As a result, Shock 6 is the industry’s most advanced fully Windows compliant, 32 bit software that a user can find while being simple to use.

The user can choose from a number of test formats including CVP (constant velocity plot), PVP (peak velocity plot) and MCVP (multiple constant velocity plots).  With the MCVP, the user can also decide to run at various speeds to characterize a damper for different road events or choose to run at a given speed multiple times and thus collect many different settings for use with adjustable dampers.  Or combine these into a batch test for additional information.

Shock 6 allows for a warm up cycle using temperature or time as the trigger.  The user can perform a gas force measurement in the case of dampers with gas chambers done at mid stroke or use multiple points to create a curve that takes into account displacement of the shaft.  Seal drag testing through a range and velocity for friction testing.

Use predefined graphing, Force vs. Velocity, Force vs. Displacement or Signal vs. Time and even create your own using Signal vs. Signal. Live screen, Validation, Average are all part of the standard software.

SPRING 6: Manual Spring Testing

Developed in conjunction with Shock 6, Spring 6 has been developed over the last 15 years to provide the user with all the function they need to collect the information they require to characterize springs.  As is all Roehrig software, it is user driven and developed in accordance with needs as well as goals.

By combining a user defined preload and test range, the software allows for a large array of data presented in easy to read graphs all at the click of a mouse.  By using a preload, the spring can be viewed in a test range realistic to its given use while ensuring that it has met its given initial load.  This is all done dynamically to give more accurate to the real world results.

Able to do pass / fail validation inspection.

ASR: Force Based Spring and Elastomer Testing in Compression and Extension

The Advanced Spring Rating software is one of our newer products.  It was developed in conjunction with our NASCAR teams measuring coil bind and our valve spring manufactures wanting to quantify spring behavior.  The ASR software allows the user to work in the force domain so that they collect data in the compression and extension portions of spring travel.  With its unique ability in the industry to collect and display the rate data based on a semi-dynamic test, the user is given a better view of the spring.  Data can be viewed in either graph format or number report tables with the click of a mouse.

It is able to do a constant triangle wave input at a given velocity to develop a hysteresis curve in the compression and extension portion of the springs travel.  It can also do the old industry standards step test and point test.  Lastly, it can perform a statistical batch test complete with final results in statistical mode to discern quality of a given batch of springs.  For all tests, the data is available to be queried in a number of ways to give the user the power to retrieve any amount of data in the range they need to quantify.

BAR: Torsion Bar Rating

Like the spring software Bar allows the user to define a preload and test range to twist a torsion bar. Data can be viewed in a bar Rate vs. Load or Rotation, or Torque vs. Rotation. Like all REI program Signal vs Time or Signal vs. Signal graphs are available as well as user definable math channels. The user can write math channels to plot spring rates at the end of a torsion bar arm or travel at the end of a arm.

DLT: Durability Life Test - Durability Running with nested Performance Tests

Durability Life Testing Software is capable of running on any REI hardware platform, including RoSA, EMA and SYD series.  Using a Test Setup Wizard, the user can easily setup a customized extended test profile for up to 4 specimens consisting of 2 independent cyclic durability steps of any duration, with the option of conducting nested performance tests after each block of cycles.  Force and Temperature Under peak and Over peak Limits can be customized for each durability step and digital outputs can be controlled for greater testing flexibility. 

 The main operating screen provides the user with instant feedback including cycle counts, limit status, trend graphs, as well as constantly updating force vs. displacement and force vs. velocity plots.  Results are saved to preformatted reports for future reference.  Performance test results can be viewed from another remote computer even while the durability test is still running, can be over laid for comparison, and are compatible with REI's standard Shock program for greater flexibility. 

GLT: General Line Test - Production Line Characterization

The GLT, General Line Test series has been specifically written for use in the production environment to easily setup and run standard characterization tests.  Current capabilities include Touch screen operation, batch file setup with variable test parameters, statistics with automatic limit calculations, dynamic analysis as well as PLC integration for automation and part handling.

QLT: Quality Line Test - Pass / Fail Analysis

For quality control testing where a simple red/green light pass fail is required. QT overlays the standard Shock program. Using the standard test and validation in Shock 6 a user can design a QC test. Operator just has a start test button to depresses,, after the test is run a pass/fail light will inform the operator if the test specimen falls within the validation parameters.

TIME: Simple signal collections

Roehrig Engineering’s very own version of data acquisition software driven by the user.  This can be used in conjunction with Shock to collect channels using triggers setup by the operator.  Information is then displayed using Shock 6 in the Signal vs. Time area of the software.

Shock for EMA: Variable Wave Form Generator

This software has the look and feel of Shock 6 with the advanced ability to create or import a variable wave form using an integrated advanced motion control software.  Using the built in wave form generator, the user can easily create a given test in a matter of minutes to perform Square wave, Sine on Sine, Variable Sine, Triangle and frequency sweeps as well as any of the standard features found in Shock 6.  Additionally, the user can import their own wave form driven by *.txt, *.csv, *.xls or *.asc  thus allowing for track displacement playback for real world testing.
