Notice of RetractionResearch on optimization of running performance for high speed forklift

The first round trial-manufacture prototype of high speed forklift has some disadvantages, such as obviously vertical vibration, deficiencies in steering aligning, and so on. These disadvantages confine the application of high speed forklift in actual engineering. Therefore it is urgent to improve and optimize high speed forklift. On the basis of analyzing the influence factors according to corresponding automotive theory, the constructing rules for the simulation model are put forward. The virtual prototype, which is the CAE model of dynamic simulation about matching analysis between the chassis and body, is constructed on the platform of ADAMS/Car. The constructed virtue prototype has the modularization framework and the data communication interfaces between the model units. Then the simulation about vertical vibration and steering aligning of the vehicle's running performance is implemented. Aiming at the performance optimization of the vehicle's vertical vibration and steering aligning, the technical measures about improvement design of the suspension system in chassis are put forward. At last, the ride comfort and steering stability of high speed forklift are validated by experiments.
