BRAKING PERFORMANCE OF AIR SUSPENDED CONVERTER DOLLIES

The Roaduser Autosim Truck Engineering Dynamics (RATED) computer simulation models were used to simulate the performance of hinged and rigid drawbar tandem and triaxle dollies under braking. The results from the simulation showed that an air-suspended tandem converter dolly could pitch significantly under braking when compared to mechanically suspended dollies. Triaxle air suspended dollies were found to pitch somewhat less than the tandem air-suspended dolly and generated a lower longitudinal force in the coupling. This indicated that the triaxle dolly has better brake balance and should be encouraged by allowing the weight increase. Rigid drawbars on converter dollies reduce the amount of dolly pitch and hence have better brake balance. It was found that tandem axle air-suspended converter dollies perform significantly better if they use a rigid drawbar. This paper presents the results of the braking performance conducted with the RATED system, briefly compares these results with test data and discusses how key results can be transferred into practice.
