“…The complete tyre model has been used to calculate the force and moment system corresponding to running conditions for which data has been published [2,7,24,25,27,28]. In each case, the results compare reasonably with the originals, providing reassurance that the generic model with its parameter values can be employed with confidence.…”

Abstract.Starting from an existing advanced motorcycle dynamics model, which allows simulation of reasonably general motions and stability, modal and response computations for small perturbations from any trim condition, improvements are described. These concern (a) tyre/road contact geometry, (b) tyre shear force and moment descriptions, as functions of load, slip and camber, (c) tyre relaxation properties, (d) a new analytic treatment of the monoshock rear suspension mechanism with sample results, (e) parameter values describing a contemporary high performance machine and rider, (f) steady-state equilibrium and power checking and (g) steering control. In particular, the "Magic Formula" motorcycle tyre model is utilised and complete sets of parameter values for contemporary tyres are derived by identification methods. The new model is used for steady turning, stability, design parameter sensitivity and response to road forcing calculations. The results show the predictions of the model to be in general agreement with observations of motorcycle behaviour from the field and they suggest that frame flexibility remains an important design and analysis area, despite improvements in frame designs over recent years. Motorcycle rider parameters have significant influences on the behaviour, with results consistent with a commonly held view, that lightweight riders are more likely to suffer oscillation problems than heavyweight ones.

“…The brush model is a simplified tire physical model, 12,13 which can reflect the basic mechanical characteristics of the tire. Combining the results of the above test and finite element simulation, this paper establishes a brush model considering the main elasticity of the carcass, 14 which includes the lateral translation deformation and the torsional deformation of the carcass as is shown in Figure 12.…”

“…According to equation ( 9), the relationship between temperature and tire corner stiffness is as form of the Exponential equation, so in the empirical modeling process, the relationship between temperature and corner stiffness as the Exponential equation is set as the basis for modeling. The expression of the cornering stiffness K y in the UniTire model is shown in equation (11), multiplied by K y tempe , and its expression formula is shown in equation (12). Finally, the expression of the cornering stiffness model of the UniTire model considering the influence of temperature is finally obtained, as shown in formula (13).…”

Based on the results of tire handling test, the cornering properties of the tire at small side slip under different temperature are obtained, and the variation law of the parameters of tire cornering characteristic with the temperature is obtained. By establishing a tread temperature model and finite element tire model considering the influence of temperature, the mechanism of tire mechanical properties with temperature is clarified, and the expression of tread stiffness and aligning stiffness considering temperature is obtained. Then, based on the above expression and the tire mechanical characteristics with temperature, a complex brush model is established and the relationship between the temperature and the tire cornering properties is obtained. The relationship is used as the basic expression formula to establish the UniTire cornering model considering tire temperature. In order to verify the correctness of the model, four kinds of temperature state cornering data are used for parameter identification, and the tire cornering properties in the other two temperature states is predicted. The error between the simulation results of the prediction model and the experimental results is very small, which effectively proves the predictive ability of the UniTire cornering model considering tire temperature. This research is helpful to improve the application of UniTire model under different temperature condition.

Based on the results of tire handling test, the cornering properties of the tire at a small range of steer angles under different temperature are obtained, and the variation law of the tire cornering characteristic parameters with the tire temperature is obtained. By establishing a tread temperature model and finite element tire model considering temperature, the mechanism of tire mechanical properties with temperature is clarified, and the expression of tread stiffness and aligning stiffness considering temperature is obtained. Then, based on the above expression and the tire brush model considering the tire temperature state, a complex brush model is established. Through the model derivation, the relationship between the temperature and the tire cornering stiffness is obtained. The relationship is used as the basic expression formula to establish the UniTire cornering model considering tire temperature. In order to verify the correctness of the model, four kinds of temperature state cornering data are used for parameter identification, and the tire cornering properties in the other two temperature states is predicted. The error between the simulation results of the prediction model and the experimental results is very small, which effectively proves the predictive ability of the UniTire cornering model considering tire temperature. This research is helpful to improve the application of UniTire model, and provide theoretical and technical support for UniTire model indoor and outdoor expansion applications
