“…Stressstrain points should be recorded electronically and exported to a text file, for later use in material modeling procedures. As belt cords may be subjected to tension during the tire manufacturing process [30], it may be appropriate to impose a certain amount of preload in the beginning of the test, or to slightly adjust (shift) the stress and strain values of the test data obtained without preload. In order to enable the use of viscoelastic/viscoplastic cord models, the unloading curve should also be recorded.…”

“…Cho et al [30] studied truck tire stress using a global-local approach to FEA. In order to represent cord tension as well as cord bending, the results obtained using a global tire model were used to impose boundary conditions on the local tire model, which employed one of the equivalent cord models proposed in the study.…”

Tires are, in essence, a composite structure made of reinforced elastomers. As in other composite structures, the accuracy of finite elements (FEs) in predicting the performance of a tire is highly dependent on the validity of the material models chosen to describe the mechanical behavior of its constituents. This paper concentrates on the material modeling of tire reinforcements, and analyzes several material models, namely linear, Yeoh and Marlow, which are quite common in these investigations. A realistic tire is considered as a general system and the most relevant results are discussed concerning precision, computational efficiency and complexity in parameters identification. The advantages of non-linear material models, especially of the Marlow model, are outlined. To the authors' knowledge, no study has addressed the abovementioned aspects of the application of tire cord models in FE analysis of tires in such detail or directly compared the performance of cord models in a realistic example.

The paper is aimed to analyze and get a further understanding of the dynamic characteristics of the tire by means of computing modal analysis. A tire modal testing system is built on the basis of the previous studies. We also attempt to study how the amplitude of exciting force and loading changes affect the tire modal test, which lays a foundation for applying the tire modal test into practical use. Besides, the relations of experimental modal and computing modal will also be analyzed. The analysis and application of the tire modal lay a solid foundation for medium-high frequency tire mechanical model which is being established by our research group. And it takes advantage of HYPERMESH and ANSYS to set up the finite element model of the tire and to analyze the tire structural dynamics, laying a foundation for setting, recognizing the correctness of experimental modal parameter as well as studying the relationship between calculating modal and experimental modal. And it also studies the law of tire's dynamic characteristics and its reason. The third part makes a summary of the full text.

“…A precise tire-road interaction modeling method is crucial for understanding and estimating the tire camber performance. Over the past decades, many efforts, including empirical method, analytical method and numerical simulation, have been focused on the study of pneumatic tire modeling [11][12][13][14][15][16][17][18][19][20][21][22]. FEM has been utilized extensively in the simulation of tire models due to its capability to solve complicated structural behaviors combining the nonlinearity of a material and geometry.…”
