Abstract: The objective of this thesis is to develop simulation-based design strategies for optimizing the selection of active, semi-active, and passive components for industrial steer-by-wire (SBW) applications. Experimental steering data is collected from an instrumented Honda Accord (1987 model) and used to validate a lateral vehicle model. This model is used to investigate the tactile feedback performance of various SBW configurations at specific driving conditions. Although peak performance is obtained with fully active components (direct-drive electric motors), comparable performance can be obtained using a combination of passive springs, semi-active dampers, and active motors with a 16.3% reduction in cost and an 87.7% reduction in electrical energy required.
