Finite it is formed with the multiple nodes splitting creation manner of the tire model and performance

摘要

PPROBLEM TO BE SOLVED: To shorten the time required when many tire models are prepared by easily preparing the tire models of changed shapes. PSOLUTION: The tire model becoming reference (reference tire model) is prepared (step S101), and an inner surface shape of a molding die is set (step S102). Subsequently, a corresponding relationship of an outer joint point existing on an outer surface of the reference tire model and an inner joint point existing on an inner surface of the reference tire model and restricting thickness of the reference tire model is determined (step S105). Thereafter, the outer joint point is fitted to the set outer shape (step S106), and the inner joint point is moved (step S107) while maintaining a relative position relationship with the inner joint point corresponding to the outer joint point. Further, it is moved through the joint point other than the outer joint point and the inner joint point (step S108). PCOPYRIGHT: (C)2009,JPO&INPIT
