A Nonlinear Model for Top Fuel Dragster Dynamic Performance Assessment 2008-01-2961

A dynamic model of a top fuel dragster performance is presented. This model represents a four-degree-of-freedom system involving a set of nonlinear differential equations of motion. Drive-train angular motion, pitching chassis motion, rear tires deflection and diameter growth, variable mass moment of inertia, and traction characteristics are included. Engine characteristics and set-up are also incorporated in the model. Numerical simulations are made to investigate the effect of aerodynamics and engine initial torque on performance. The numerical results suggest that a reduction in elapsed time can be achieved if the conditions are appropriate.
