Development of Standardization and Management System for the Severity of Unpaved Test Courses

The vibration environment essentially accompanied by vehicle operation on theground is determined by the shape of road surface, which is called as profile. This paperfocuses on the development of profile measurement and severity analysis system forunpaved test courses. In general, the profile and severity of unpaved road is an importantissue in the reliability of endurance test. In order to measure and maintain unpaved roadprofile and severity, it is necessary to develop a profilometer system. The developedprofilometer system is composed of data processing computer, power unit, air compressorand sensors(encoder, vertical gyro and laser displacement). This study presents themeasuring system configuration, measurement principle of road profile and analysismethod of road characteristics used at CPG (Chang-won Proving Ground) for this purpose.In order to standardize and manage the severity of unpaved test courses, neural network isapplied.
