SIMULATION OF A TANDEM AXLE TRACTOR-TRAILER WITH EXPERIMENTAL VALIDATION

A digital computer simulation of an on-highway tandem axle tractor-trailer has been developed. The mathematical model is presented in state variable form and includes non-linearities, such as suspension friction and shock absorber characteristics. The primary purpose of the simulation is the evaluation of suspension characteristics and their effect on truck ride. Comparisons showing good correlation between simulation and experimental results are presented for transient runs of the tractor- trailer over disturbances such as 2 x 4's and ramps. (A) This paper was presented at the Combined Commercial Vehicle Engineering & Operations and Power Plant Meetings, Chicago, Illinois, June 18-22, 1973.
