Design Method of Test Road Profile for Vehicle Accelerated Durability Test 931911

This report explains the basic theory of designing the accelerating durability test road and the role of each factors contributing to the test road surface profile. Also this road is designed by considering the charactors of vehicle suspension system and conditions of driving. In test road, the factors affecting to the vehicle structural durability are correlation among surface shape of road profile, frequency of vehicle suspension system,distribution of axle twist angle and vibration of road profile height.
Road PSD magnitude and frequency delay is used to control these factors relation.
