Simulation Analysis of Lateral Relaxation Length of Passenger Car Radial Tire
A simulation analysis of the lateral relaxation length of 215/60R17 96H DH16S passenger car radial tires was conducted.The results showed that using two simulation methods[simultaneously applying instantaneous sideslip angle to the tire and rim(referred to Method 1)and only applying instantaneous sideslip angle to the rim(referred to Method 2)],different lateral relaxation lengths of tires could be obtained,and the results of Method 2 were in better agreement with the experimental results.With the increase of the load,both the maximum lateral force and lateral relaxation length of the tire increased.With the increase of the inflation pressure,the maximum lateral force of the tire changed little,and the lateral relaxation length of the tire decreased.
