<p><P>PROBLEM TO BE SOLVED: To reduce time for preparing an analysis model for evaluation of characteristics, performance, etc. <P>SOLUTION: The tire model preparation method includes: a procedure (step S101) wherein a tire to be analyzed is divided into a plurality of elements and a first tire model is prepared; a procedure (step S102 to step S104) wherein the mass density and elastic modulus of the prepared first tire model are adjusted to set the natural frequency of the first tire model within a predetermined range; and a procedure (step S105) for preparing a second tire model wherein the tire to be analyzed is divided into a plurality of elements so that the circumferential division number may be larger than the first tire model to set mass density and elastic modulus to those when the natural frequency becomes within the predetermined range. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
