Three-Wheeled ATV – A No-Suspension Rigid Rider System, Part I: Modeling and Parameter Values 841058

This paper presents the dynamical equations of motion governing a six degrees-of-freedom mathematical model of a three-wheeled all-terrain vehicle/rigid-rider system. The parameter values associated with two commercially available three-wheeled all-terrain vehicles, a 1980 Honda ATC 110D and a 1980 Kawasaki KLT 200, are presented. In addition, tire properties such as non-rolling vertical stiffness, cornering stiffness and damping ratio for a 22×11-8 Ohtsu tire and a 22×11-8 Goodyear tire are given. These parameter values are used to simulate the motions of the vehicle/ rider system with the results presented in Part II (1)*
