Research on Steering Safety Strategy of Electric Forklift

摘要

A detailed discussion about lateral stability and longitudinal stability of electric forklift had been done. Besides, this thesis introduced the control requirements of the lateral stability firstly, and then calculated the max safe steering speed on the critical overturning state secondly, and then gave the relationship between the safe steering speed, the steering torque, the load of the forklift and the steering real-time speed. Finally, the optimized factor and the optimized slope were determined based on fuzzy control theory to gain the expression which can optimize the speed.
