电动叉车的直接驱动策略研究

Studies on direct driving strategy of electric forklift truck

针对电动叉车的行走驱动提出1套全新的直接驱动策略,使电动叉车的结构最简单化,驱动效率和灵敏度大大提高。根据电动叉车装卸货物时要求具有良好低速性能的特点,研究并提出直接驱动方案对驱动电机的要求;针对采取直接驱动方式后所产生的新技术问题,阐述了几种控制策略,并进行了分析对比,使电动叉车的行走更具有平滑性和鲁棒性。

Aiming at the motion driving of the electric fork lift truck,a set of new direct driving strategy is put forward,which then greatly simplifies the structure of the electric fork lift truck and improve the driving efficiency and sensitivity. According to the characteristics that a good low-speed performance is required when the electric fork lift truck handle the goods,the design requirements of the direct driving scheme for driving motor are researched and put forward; aiming at the new technical problems when the direct driving method are adopted,several control strategies are stated,and analysis and comparison are performed,thus to make the electric fork lift truck to move with more smoothness and robustness.
