Abstract
A general nonlinear procedure for yaw-roll-pitch models oflog-hauling trucks, with different configurations, is developed based onthe methodology of a general purpose computer code DYNOCOMBS (Dynamicsof Constrained Multibody Systems). To implement the constraint equationsfor the special design feature in log-hauling trucks, a procedure isdeveloped allowing the use of the code for general-purpose dynamicanalysis of the trucks. The BNPS (Bakker, Nyborg, and Pacejka andSmithers Scientific Services, Inc.) tire model for combinedtire-cornering and braking forces is used in the simulation. Thevalidation test is conducted by comparing the numerical results offree-rolling cornering responses of the system with both of the measuredresponses in field tests and the simulation results from CSTT (Centrefor Surface Transportation Technology) model. The simulation study iscarried out on three cases of evasive maneuvers with combined corneringand braking.
