Abstract

Steer-by-wire technology essentially eliminates the use of traditional mechanical controls like steering linkage, cables, and hydraulic pressure to turn the wheels. It incorporates features such as, but not limited to, electronic signals to turn the wheels and sensors for determining the required steering force for the specific application. When attempting to move heavy vehicles that require rear wheel steering, steer-by-wire would allow the most optimal drive performance during tight turns. A steering force actuator, electric control unit, and electronic motors would be added to the vehicle to allow a turn radius of 90º; 45º from the front tires, and 45º from the rear tires. It is an increase of 22.22% from its current 70º total turn radius. Although a traditional hydraulic system could endure the heavy load, steer-by-wire technology allows the driver to receive haptic feedback and adjust in real time. While steer-by-wire is already being used in vehicles like forklifts and front-end loaders, it is not used for parade float applications. This goal of this study is to design a steer-by-wire based technology for improving the turning radius of parade float vehicles. The study involves extensive analysis of steer-by-wire technologies along with developing conceptual designs. The design will be modeled using CAD software and analyzed using CAE Finite Element Simulation tools. The expected outcome of the study includes an innovative knuckle design that would be linked to the hydraulic four-bar linkage which assists rear-wheel steering.
