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。
The change of the momentum of the storage material in the silo discharging process was introduced into the analysis, and the concepts of “pressure arch” and “discharge pressure increase coefficient” were proposed, and the pressure increase law during discharge was studied. The formulae for calculating the pressure increase during unloading and unloading are calculated and the calculated results are in good agreement with the measured results.
