PROBLEM TO BE SOLVED: To precisely predict tire performance on any type of the ground. SOLUTION: A tire model is created, and a field model is created based on measured data after measuring an actual field (steps 100-104). Boundary conditions are set (step 108), and the deformation of the tire model is calculated (step 110). The deformation of the field model is calculated in consideration of the moisture of the ground (step 112), and a friction force applied to the tire is calculated (step 116). The boundary face of a field is recognized according to the deformation of the tire model and the boundary conditions are added (step 118), and a surface force added with the friction force is applied to the tire model, and results are outputted and evaluated (step 122). Such a result output and the evaluation of the tire performance are repeated (steps 122-134). COPYRIGHT: (C)2009,JPO&INPIT
