Fmin is thus a full-fledged Vehicle Simulation System that controls both the statics and dynamics of the truck at all locations within the aisle. Fmin directly limits each wheel track’s influence on the truck’s angular displacements, angular velocities, and angular accelerations around both its pitch and roll axes. The Fmin System (developed by Allen Face in 1979) is used to control the wheel track profiles on all Defined Traffic floors. ![]() The six surface variables uniquely limited by Fmin (no other system employs this dynamic simulation approach) control the movements of a truck as it moves across the floor (for more information on the six variables go to ‘Specifier’s Guide to F-Numbers’) For this reason, the specification formats employed in DIN 15185 and VDMA are not effective. In this method, ‘transpose’ command is used to find out the transpose of the matrix. Unfortunately the gaps under 1, 2, 3, and 4 meter long straightedges are not the variables that influence truck movements. Steps: Accept input matrix by using square matrix (Input 23, 32, 11 22 3 2 16 39 21 32 4 1 Apply the operator on the input matrix ( output matrixinput matrix.’) Display the output matrix. The following table can be used as a reference every time you want to change to another key. ![]() The result will be this: D - G - Bm - A - G - D. As a consequence, floor requirements have to be well-specified and those variables that affect the truck’s movements must be limited. If we have the chord progressions: C - F - Am - G - F - C in the C Major and want to transpose it to the key of D Major we have to change every chord by two semi-steps.
