Road Simulator
Before you begin
There are two methods of using a SWIFT on a road simulator.
The traditional “non-spinning” or “fixed” mode relies on the orientation of the
SWIFT during road simulator use maintaining the same orientation relative to the
anti-rotate position used during road testing. The SWIFT outputs are given in set
coordinates relative to the SWIFT sensor orientation, and no angular
transformation is applied to the SWIFT outputs. This is the typical method of use
for larger vehicles where the angle variations of the anti-rotate bar are negligible
during road testing.
The second method uses the SWIFT in a “spinning” mode. While the SWIFT
itself is not spinning, the outputs from the SWIFT are passed thru the rotational
transformation processing in the TI box, and the actual angle of the SWIFT
relative to the encoder anti-rotate is taken into account. This method is best
when there are significant angle variations of the anti-rotate bar during use, as is
common on many smaller, high deflection recreational vehicles.
Depending on which mode you are using, you must load the correct calibration
file into the TI boxes. Two calibration files are provided with each TI box:
• For fixed (non-spinning) mode the calibration file name is
serialnumberf.cal.
• For spinning mode (applications that experience high displacement and
pitch) the calibration file name is serialnumbers.cal.
Clean all surfaces. It is critical that all surfaces be free of stones, burrs, and
grease.
Do not pressure-wash the transducer or clean it with solvents.
Pressure-washing the transducer or cleaning it with solvents can damage it
or degrade the silastic seal and may void the warranty.
Using strong cleaners or solvents can damage the RTV seal and may void
the warranty.
Use only a soft sponge or brush with non-metal bristles and a gentle detergent
(such as dish soap) to wash the transducer.
