MODELING THE DYNAMIC BEHAVIOR OF A WHEEL AS A FUNCTION OF SOIL IRREGULARITIES

摘要

Method for modeling the dynamic behavior of a motor vehicle wheel according to a road profile (10) measured in front of the vehicle, comprising a first step carried out by a modeling function of the tire (4), giving a height variation calculation theoretical of the wheel center (14) according to the measured road profile (10) and the speed of the vehicle (12), from a tire contour model, then a second step performed by a dynamic wheel modeling function (6) giving a first calculation of the position of the wheel center (16), and then loop iterations of this second step taking into account a calculation of the suspension force (18) carried out by a dynamic modeling function of the vehicle ( 8), to successively renew this position calculation with the values of the previous iteration and the new value of the road profile.
