In this report,we examined the generation system and measurement methods of the exciting force generated by automobiles during transit over sections of road rough surface and,furthermore,studied the time characteristics of the exciting force and peak impact force,as well as other factors.As a result,we were able to clarify the following. 1. Direct measurement methods using force sensors corresponded favorably with indirect measuring methods calculated from vibration response at points on the road surface (transfer function method) 2. In regard to the characteristics of exciting force,though peak impact force had a tendency to increase as the velocity increased.in regard to impulse.there was a tendency of decline.and impact frequency was in the vicinity of the 10-50Hz band. 3.Considering the exciting force generation system as a 3-mass system made up of the suspension device,tire and the road bed,we found that when the vibration response of the mass portions of the upside and down side of spring were measured at the time the wheels transited the rough surface,results were obtained that indicated a favorable correspondence with the exciting force measured using direct measurement methods.
