3、ing, the need for optimization of six-bar linkage design. To analyze the forklifts steering performance, the use of ADAMS, the steering mechanism on the truck the modeling and simulation, measuring the angle of the steering error; to achieve a steering mechanism of the parametric modeling, the steer

4、ing angle error of the cumulative goal of minimizing function of the steering mechanism was optimized, and the establishment of a forklift vehicle model, measured outside the steering wheel forklift model error and the vehicle turning radius curve, analysis of the forklifts steering provided. And the results to optimize the design parameters to create the forklift vehicle ADAMS model, simulation results show that the effective optimal design.
