Title:
接触特性の評価方法
Document Type and Number:
Japanese Patent JP6993201
Kind Code:
B2
Abstract:
To provide a method for evaluating a contact characteristic of a road surface model and a tire model, by making out the road surface model having macro-irregularity by a new method.SOLUTION: A step of making out an irregular road surface model includes a step of specifying a low frequency area in power spectrum density distribution of irregular data of a road surface including macro-irregularity and micro-irregularity, a step of making out a new function capable of approximating the distribution of the low frequency area by superposing a trigonometric function of a frequency of the low frequency area when analyzing a power spectrum and a step of making out the irregular road surface model composed of macro-irregularity based on the made-out new function.SELECTED DRAWING: Figure 3
