摘要

PPROBLEM TO BE SOLVED: To improve accuracy of steady-state transport analysis in analyzing rolling motion of a wheel or other rotational bodies by steady-state transport analysis. PSOLUTION: A two-dimensional shape of a meridian section including a rotational axis of a wheel is developed in a circumferential direction of a wheel to generate a simplified wheel model (step S101). In the meridian section including the rotational axis of the generated simplified wheel model, the simplified wheel model is divided into at least two areas (step S102). Rigid body properties of the simplified wheel model is adjusted to the rigid body properties of an actual wheel (step S103-S105) by adjusting mass density in each divided area. A natural frequency of the simplified wheel model is adjusted to the natural frequency of the actual wheel by adjusting an elastic modulus in each divided area (step S106-S108).
