摘要： PROBLEM TO BE SOLVED: To evaluate accurately the traveling condition of a vehicle, with respect to the slippage on the contact area between a tire and a road surface which varies at each moment, during the steering of an automotive vehicle.
SOLUTION: Acceleration data at a predetermined position of the tire, produced by the tire-receiving external force from the road surface, while the vehicle travels on the road surface are acquired in time series. A spectrum of the acceleration is obtained by performing frequency analysis on the time series acceleration data. The peak value in the frequency range of 500-1,500 Hz, corresponding to the frequency of a squealing noise produced by the tire, is detected, and the traveling safety of the vehicle is evaluated, according to the peak value detected.

摘要： PROBLEM TO BE SOLVED: To quantitatively evaluate the relationship between the microscopic structures and dynamic properties of real complex and various composite materials.
SOLUTION: A specimen of a composite material is magnified using a microscope to acquire a microscopic image of the composite material (step S101). Once a two-dimensional finite-element model is created based on the microscopic image, a material constant for the composite material is set (step S102), and an analysis is performed using a finite-element method of analysis which has prior experimental results of the composite material to be analyzed (step S103). An S-S curve obtained by the analysis by the finite-element method is compared with an experimentally obtained S-S curve (step S104); when the curves do not match (step S104; No), the two-dimensional finite-element model created is modified (step S105). Using the two-dimensional finite-element model modified, the dynamic properties of the composite materials is evaluated.
