Multiscale structural analysis | Automotive Testing Technology International
The composite nature of many of the components that comprise the typical tire structure requires sophisticated modeling capabilities. Micromechanics has been used to efficiently analyze tire performance on the macroscale by minimizing the loss of information afforded by elements at much smaller scales. This article discusses two examples of leveraging multiscale structural analysis technologies to analyze tire performance at multiple scales. The first example is the micromechanics analysis of the bead structure, which facilitates efficient high-fidelity bead unseating simulations. The second example is a cross-sectional analysis of tire tread-band structural design.
