With a 50" diameter roll set, a maximum speed of 225 mph, and a horsepower
measurement rating of 1,750 hp, the MD-1750 is by far the fastest and most
powerful dynamometer available in its class. The optional single or twin eddy
current power absorption feature allows for "steady state" testing at various
speed and torque outputs, making the MD-1750 a dynamometer in the truest sense.
The MD-1750's inertial based testing capability provides a practical and
efficient means to gauge vehicle performance. Inertial based performance
testing involves accelerating a cylindrical mass with a known inertia at
wide-open throttle. In the case of the MD-1750, the immutable inertia encased
in a 50" diameter roll, or drum, acts as the road-load mechanism. The rate at
which the vehicle is able to accelerate the drum provides insight into the
amount of energy transferred from the tires to the surface of the drum. Speed
and torque combined produce instantaneous wheel horsepower data. These data are
then plotted against time, speed, or distance to produce easy to use graphs. A
database keeps track of testing records for future baseline test comparisons.
More advanced testing capabilities are available with Mustang's optional eddy
current power absorption feature. Eddy current power absorption enables the
system to test vehicles at variable throttle-positions, speeds, and torque
outputs. The torque value read from the load cell is combined with roll-speed
picked up magnetically at the roll shaft to calculate the exact force being
applied at the vehicle's wheels at any time throughout the test sequence.
Unlike friction-type load control "devices" offered by competing manufacturers,
our eddy current absorbers and advanced closed-loop computer control system
enable the user to carefully control the road load applied to the vehicle under
test by increments of horsepower or torque
