To analyze the forklift39。 to achieve a steering mechanism of the parametric modeling, the steering 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 forklift39。 simulation。 29 優(yōu)化模型 ...................................................................................................................................................................29 5創(chuàng)建整車模型，仿真叉車的轉(zhuǎn)向運動軌跡 ..................
