VEHICLE AERODYNAMIC FORCE COMPUTATION APPARATUS, VEHICLE MOTION ANALYZER, AND VEHICLE SUSPENSION CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To appropriately analyze the action of an aerodynamic force to which a vehicle is subjected.;SOLUTION: A vehicle aerodynamic force computation apparatus 10 is constituted of a computer, and data 20 on the coefficient of acceleration terms acquired by wind tunnel testing, etc. and others are stored in its storage part 18. A CPU 12 includes a condition acquisition processing part 24 for acquiring analysis conditions a modeling processing part 26 for dynamic aerodynamic modeling of an aerodynamic force acting on a vehicle through the use of a coefficient of acceleration terms stored in the storage part 18; a variation component computation processing part 28 for performing computations on variation components, with the aerodynamic force acting on the vehicle as an external force; and an action computation processing part 30 for computing each external force acting on the vehicle, on the basis of computed variation components. It is further also possible to analyze the motion of the vehicle by putting computed external forces by the aerodynamic force into an equation of motion and also possible to control the suspension of the vehicle.;COPYRIGHT: (C)2011,JPO&INPIT
