Abstract:

A generalized mathematical model which characterizes the dynamic behavior of five different classes of highway vehicles is described in this report. The model consists of a series of interconnected masses, springs, and dashpots and is used to predict the magnitude, duration, and location of dynamic wheel loads applied normal to the roadway surface by the wheels of single unit and articulated vehicles operating under various conditions. The model may be forced by a simulated road profile made up of an array of bumps with different sizes and arrangements in each wheel path, or more realistically, it may be forced by a natural profile recorded in the field by a road profilometer and converted to a suitable digital format. Besides the roadway profile, required input for the model consists of static wheel loads, numerical quantities assigned to the physical characteristics of the vehicle suspension system, and axle spacing. A computer program which solves the sets of differential equations used to describe the motion of each vehicle and calculates the forces between the tire and the road surface has been written in FORTRAN language for the CDC 6600 computer and is documented with example problems.
