ANALYSIS DEVICE OF AERODYNAMIC CHARACTERISTIC, AND ITS ANALYSIS METHOD

摘要

PPROBLEM TO BE SOLVED: To evaluate a force acting on each element of a shape model of a vehicle body in consideration of the whole shape of the vehicle body, to accurately and certainly present a part requiring correction to an analyzing person, and to increase the efficiency of correction work or the like. PSOLUTION: The shape model of the vehicle body is read (S101), a shape model B is created by dividing the surface of the shape model of the vehicle body into elements, and an analysis model C is set by arranging this shape model B in a calculation space A (S102). An analysis condition such as a boundary condition in the analysis model C is input (S103), aerodynamic calculation on the surface of the shape model B of the vehicle body divided into elements is performed using the analysis model C, and a force acting on each element is calculated (S104). Then, yawing moment Mzi per unit area of each element is calculated (S105), and the yawing moment Mzi of each element in the shape model B of the vehicle body divided into elements is displayed by distribution (S106).
