摘要
结合穿梭车理论模型,通过ADAMS对穿梭车进行运动仿真,分析不同速度控制策略下穿梭车的运行性能,确定了不同速度对穿梭车运行性能的影响以及穿梭车的启制动的最佳加速度。同时结合仿真分析结果,设计了一种非等加减速度控制策略,在确定行程下,分析了穿梭车启动加速度和最大运行速度与穿梭车运行时间的关系,确定了最佳速度控制方案,并与常用的等加减速度控制方案进行比较,结果显示,该方案能有效缩短穿梭车运行时间,提高搬运效率。
Considering the theoretic model of rail-guided vehicle, motion simulation is performed on RGV in ADAMS to analyze the operating performance of RGV under different speed control strategies, and determine the effect of different speeds on the operating performance, and the optimum acceleration of RGV at startup and braking. Based on the simulation analysis result, a non-equal acceleration and deceleration control strategy is designed. When the journey is determined, the relationship between RGV startup acceleration and the maximum running speed and RGV running time is analyzed to determine the optimum speed control proposal, which is compared with the conventional equal acceleration and deceleration control proposal. The result shows that the proposal can effectively shorten RGV running time and improve the handling efficiency.
