COSIN/io 2D Road Type: drum

COSIN/road searches for the data block $drum, and reads:
Name of input variable Unit Meaning
diameter m Diameter of the tire test drum. COSIN/road assumes an outer drum, if diameter < 0.
v m/s Rotation speed of drum surface (be sure to choose rolling_speed = 0 in the data block $sources. Otherwise, the wheel moves away from the drum).
number_cleats - Number of extra cleats on drum (number_cleats = 0 allowed)
cleat_height mm Height of extra cleats.
cleat_starting_angle deg Drum angle coordinate of 1st cleat.
cleat_length mm Length of cleat, measured in circumferential direction of drum.
cleat_bevel_edge_length mm Length of bevel edge of cleat, measured in circumferential direction of drum. Bevel edge has 45deg slope.
mu_factor_cleat - Friction modification factor on cleats.
acceleration_time s Optional time span at beginning of simulation during which the drum is accelerated to nominal speed.
