摘要
研究了各种抓斗卸船机生产率计算方法,对比分析了其优缺点和适用场合,基于机械性能计算方法,提出了抓斗卸船机性能评估新方法。建立了测试记录有效性准则,定义了一些修正系数,以有效消除物料、工况等不确定性因素的影响。计算结果表明:自动作业模式与人工作业模式相比,额定生产率提升率为3.12%,实际生产率综合提升率为7.97%,因此,新方法评估结果准确合理,并易于实现不同作业模式间的自动化程度对比分析。
The productivity calculation methods of different grab Ship unloaders were analyzed, the advantages, disadvantages and applicability were compared, a new performance evaluation method was presented based on mechanical performance calculation approaches. The validity rules of testing record were established, some modified coefficients were defined to eliminate the influence of uncertain factors such as material attributes and operation conditions. Calculation result shows that the rating productivity of automatic operation mode is increased by 3.12% than that of manumal mode, and actual productivity is increased by 7.97%, so the evaluation result is acturate, and the new method can easily compare the automation degrees of different manipulation modes. 1 tab, 11 refs.
