Study on Linear Data Monitoring Method for Tire Forces and Moments Testing Machine
The monitoring method for linear data of tire forces and moments testing machine was studied.The results showed that under small side slip angles,the effect of tire heating on the lateral force coefficient(F1)and modified moment coefficient(Ta1)was not significant.When usingF1and Ta1 to monitor test data,tire heating was not necessary.When using control tires to monitorF1and Ta1,it was necessary to consider the influence of tire manufacturing process deviation,testing machine deviation,inflation pressure deviation,and load deviation.Under small side slip angles,the adhesion coefficient of the simulated road surface had little effect on the F1 and Ta1.Under large side slip angles,the influence of the adhesion coefficient of the simulated road surface on F1 and Ta1 needed to be considered.This monitoring scheme allows the linear data of the tire torque testing machine to be monitored to determine the rationality of the test data.
