Analysis model for creating computer programs of analysis model creating apparatus and structure of the structure

摘要

PPROBLEM TO BE SOLVED: To regenerate the shape and the internal stress of a structure with high accuracy. PSOLUTION: A residual stress in the reinforcement cord of a tire is acquired (step S101), and an initial analysis model regenerating the tire shape is generated (step S102). Next, a modified physical quantity obtained by multiplying the above residual stress by an enlargement coefficient f1 is obtained. By fixing the above modified physical quantity value, a first equilibrium calculation is executed for the above initial analysis model (step S104). Next, a modified analysis model is generated by reflecting the information in regard to the deformation of the initial analysis model posterior to the first equilibrium calculation onto the initial analysis model prior to the first equilibrium calculation (step S105). Thereafter, by fixing the above residual stress, a second equilibrium calculation is executed for the above modified analysis model (step S106). The resultant modified analysis model obtained above becomes the analysis model for the above tire (step S107). PCOPYRIGHT: (C)2006,JPO&NCIPI
