ABSTRACT

This paper has given the structure, operating principle, and force analysis of electric power steering (EPS) system aimed at a type of forklift. Combing with forklift operating characteristic, three variable power characteristics curve based on steering wheel torque, real-time speed, and load is designed, so is the three dimensional diagram of forklift power gradient by using fuzzy rule. The dynamic model of EPS system and two-degree-of-freedom linear model of forklift dynamics are established. This paper presents a simulation on the basis of three variable power characteristics and dynamic model. The results show that forklift EPS system can provide appropriate power according to the changes of speed and load. It also can meet the demands of coordination between steering portability and road sense.
