Optional TIRMU (TIRe friction MUltiplier) Table Inputs for V2

The control inputs for TIRMU Friction multiplier for vehicle No. 2 are entered as time history tables of Friction Factor as a function of time on card(s) 49. The first card for each TIRMU table is the table header card which describes the size and format for the input tables to follow.

49:1

TBTirmu2

Initial time for V1's inputs.

Seconds

49:2

TETirmu2

End time for V1's inputs

Seconds

49:3

TINCT2

Time increment for TIRMU inputs for V1. One value for TIRMU is input  for each increment, so the size of TINCT1 determines the detail with which the TIRMU Variations can be described by the mathematical model. 

NOTE: If field 6 (VarInc, Option Variable increment input) is set=1, then the definition of this variable is for the number of table inputs. Maximum 50.

49:4

NTBLT2

Normally = 0.0. If < 0.0, the program reads in and ignores the TIRMU tables included following card #49.  (This option is to permit de-activating tables without having to delete the data in the tables.)

49:6

VARINC

(optional) Set =1.0 to indicate Variable time increment Table inputs. Field 4 is then used to indicate the number of inputs in the table.

The Table Header card is followed by tables containing the values for the TIRMU for Vehicle No. 1: RF, LF, RR &  LR tires  (and RRR & LRR for trailer option), one set of values per card,  and up to 50 table values.

The format for the tables is as follows:
