A METHOD FOR INTRODUCING DYNAMIC VEHICLE LOADS INTO DESIGN OF HIGHWAYS /WITH DISCUSSION/

TO PREDICT THE DYNAMIC LOAD OF A VEHICLE ON A PAVEMENT, SUITABLE METHODS ARE NECESSARY FOR CHARACTERIZING THE HIGHWAY PROFILE AND THE VEHICLE SUSPENSION SYSTEM. HIGHWAY PROFILES HAVE BEEN DESCRIBED BY USING FOURIER SERIES APPROXIMATIONS OR POWER SPECTRAL DENSITY TECHNIQUES, AND THE RESULTING FREQUENCY DOMAIN DESCRIPTIONS INDICATE THAT A SIMILAR DESCRIPTION OF THE VEHICLE WOULD BE USEFUL. THE RATIO OF WHEEL REACTION TO WHEEL DISPLACEMENT (F/X) VS FREQUENCY IS THEREFORE INVESTIGATED FOR SEVERAL VEHICLES. EFFECTS OF SHOCK ABSORBERS AND TIRE PRESSURE ARE OBSERVED. THE PREDICTION OF THE DYNAMIC LOAD USING THE PROPOSED VEHICLE CHARACTERISTICS IS DESCRIBED. A MATHEMATICAL EXPRESSION FOR THE FREQUENCY DOMAIN CHARACTERISTIC IS USED TO OBTAIN SIGNIFICANT VEHICLE PARAMETERS. ESTIMATION OF THE DYNAMIC VEHICLE LOAD INDICATES THAT A STUDY OF THE SIGNIFICANCE OF THIS QUANTITY IN HIGHWAY DESIGN IS DESIRABLE, AS WELL AS EXPERIMENTAL VERIFICATION OF THE PREDICTED VALUES. /AUTHOR/
