Virtual Pattern Optimization Based on Performance Prediction Tools

Abstract

Abstract Due to shorter development cycles and high cost pressure, the tread pattern development process is optimized by an analysis tool, which can predict the influence of the tread pattern on several tire properties. By using this tool conventional development cycles can be substituted by several virtual development cycles. The tool modules for the tire properties traction, handling, plysteer residual aligning torque (PRAT), groove wander, and noise are presented in this paper. The applicability of evolution strategy on tread pattern development is demonstrated, being another prerequisite for a future virtual pattern development process.
