KRC performs vehicle mobility
analysis for both military and non-military customers and can make design
recommendations to improve vehicle mobility of almost any type of ground
vehicle on the market today.
Using the NATO Reference Mobility Model (NRMM), KRC helps military customers
determine if their vehicle concept will meet requirements in bid specifications.
Often times the customer wants to take their vehicle’s mobility
to the next level. KRC then runs parametric studies to determine
which vehicle components or which part of the physical
design they can change to make the improvements.
KRC also uses NRMM or parts
of NRMM to look at non-military problems. One good example was a mobility
problem on an iron ore mine tailings pond. The sponsor had some vehicles
that could drive on the tailings but every so often the vehicle would “fall
through” and become immobilized. KRC was hired to investigate the
First, the soil or tailings
were tested for strength using a
simple cone penetrometer. The soil was found to be plenty strong enough
to support most any tracked vehicle, to a certain depth. But it was soon
discovered that the tailings were layered with water holes in between strong
layers. Two major findings resulted. The vehicle had to have the lightest
ground pressure possible, yet be able to carry a certain size load. The
other finding was the vehicle should not drive over the same trail repeatedly!
KRC then did a comprehensive
vehicle investigation to
identify potential vehicles the sponsor may want to
purchase. A vehicle cone index analysis was performed on ten different
vehicles. Two prime candidates were identified and volunteered to demonstrate
their capabilities. Both vehicles were successful as long as they did not
drive over the same area more than three times. More than three times,
and there was a high probability of becoming immobile!
