摘要
把筒仓卸料过程中贮料的动量变化引入分析中,并提出了“承压拱”、“卸料压力增大系数”等概念,研究了卸料时的压力增大规律,给出了计算卸料和卸料起拱时压力增大的公式,计算结果与有关实测结果吻合较好。
Considering the change of storage momentum discharge for the silo bin and intro-ducing the conceptions of 'bearing pressure arch' and 'increasing coefficient of pressurefor discharge' in the analyzing, the regularity of increasing pressure for the silo bin duringcharge and discharge and the formula of computing pressure have been deduced. The calcu-lating exarpples are given, and the calculated results are good agreement with tested one.
