【摘要】 茶叶摩擦性能的研究在制茶工程中有着重要的地位。本研究报告介绍了红碎茶对各种常用茶机材料的摩擦试验方法,分析了红碎茶的含水率、粒度、法向压力、相对运动速度、材料性能和表面状况等因素对红碎茶摩擦性能的影响。研究结果表明,红碎茶对固体材料的摩擦系数随其含水率的增加和粒度的减小而增大,随法向压力的增大和相对运动速度的减小而减小。红碎茶的内摩擦系数大于红碎茶对固体材料的摩擦系数,且随其粒度和含水量的增大而增大。更多还原

【Abstract】 This parper summed the results of the tests on friction of Black broken tea withmaterials used for Black broken tea processing.It analysed the variation in frictioncoefficient of Black broken tea with various factors such as moisture content of Blackbroken tea,grain dimensions,nomal pressure,relative valocity,properties of materialsand conditions of surface.The results of study indicated that the friction coefficientof Black broken tea to engineering materials increased with increasing of moisturecontent of tea and reducing of grain size of tea,but it reduced with increasing ofnormal pressure and reducing of relative velocity.The internal friction coefficient oftea is higher than that of Black broken tea to engineering materials,and the greatergrain and higher moisture content of tea,the greater internal coefficinet is.更多还原
