Producing Quality Computer Tools for Racers and Engine Builders since 1986
Computer Program and Electronics to Test Shock Absorbers (complete stand coming soon) - Retrofit Kit also available
for Windows 98, Me, XP, 2000, NT, Vista, Windows 7, Windows 8
Our Complete Shock Dyno is scheduled for release early in 2014. It is shown with optional IR temperature senor on right mast. It's features will include:
Watch for it's release.
We also offer the sensors, electronics and software as a "retro-fit" kit for your existing shock dyno, described at bottom of this page.
Overlay Graph of 5 Shock Tests (+ and - velocity), with Cursor to Pin Point Values
The Shock Dyno Retrofit Kit provides a load cell and length sensor, plus electronics to record both channels. Once data is recorded, you can create reports or graphs of the results. You can also overlay graphs from several different shocks for comparison.
Graph with just + Velocity
The program has several options, including:
The program is compatible with Windows XP, Vista, Windows 7 or Windows 8, which means it is easy to use and you will be able to print the results on most any printer, usually in color if your printer supports it.
The software provides for an optional Plus version, which adds several features:
Real Time Graphing - Green dots are current readings, black lines are from
"Football" graph of Force vs Position for 2 different shocks
What You Need:
Computer with Windows XP, Vista, Windows 7, Windows 8.
What You Get w Retro-Fit Kit:
The shock dyno kit expects your dyno to use a slider crank (like piston in an engine) or Scotch yoke design to cycle the shock, but does not need a variable speed motor. We very accurately measure the speed of the shock as it goes through its cycle up and down. When it is at the top of its cycle, it has stopped and then changed direction to go back down. As it goes back down, it picks up speed to maximum speed at mid stroke, then slows down when it gets to the bottom of the cycle. Then this whole process is repeated in reverse.
So, as the motor turns at a constant RPM, we can measure the velocity and force at all points of the cycle, and produce a complete shock dyno graph with force at all velocities. This makes it very easy for the electrical motor, just set it to something like 150-300 RPM with a 1" to 3" stroke, get it up to speed and press F1 on the keyboard. The software records several cycles and then presents the data.
