摘　　要：为了防止电动堆高车货叉偏载造成安全事故,设计了基于载荷传感器的电动堆高车货又偏载检测系统,并提出了一种计算电动堆高车货叉偏载的算法。该算法根据传感器的检则值快速计算出反映货叉偏载状况的偏载距离,操作者据此进行操作,避免事故发生。对计算误差的分析验证结果表明,该偏载检测算法可以将误差控制在15mm^21mm,能够满足电动堆高车货叉偏载检测的设计要求。To prevent an electric stacker truck from a safety accident arising from the partial load of its fork, a partial load measuring system using load sensors was designed, and an algorithm for partial load detection was proposed. The algorithm performs fast calculation of the partial distance reflecting the status of the fork＇ s partial load based ,on sensors ＇ ts, thus the operator can operate according to the given calculation results to secure the truck＇ s safe working. The calculation error analysis was conducted by simulation, and the results showed that the p algorithm＇s error of partial distance detection was 15mm - 21mm, meeting the design requirements of stacker trucks＇ partial distance detection was forks, which gives feasible control results.
