摘要
利用自行研制的仪器对目前我国部分地区粮食的内摩擦角、对仓壁(混凝土与钢板)摩擦系数、自然安息角等力学参数进行了测试,并通过试验分析了水分含量、颗粒粒径、地区差异性等影响因素.
The mechanical parameters of grains in partial region in China, such as internal friction angle, frie- tion coefficient in relative to the silo wall (concrete and steel plate), angle of natural repose, was tested by use of the independently developed apparatus. The influencing factors, such as water content, particle size and regional difference, were analyzed.
