摘要
影响带式输送机动态称重精度因素很多,如由输送带的黏弹性而产生的输送带张力、运行阻力等。基于黏弹性材料在动态载荷下的能耗理论,对输送带的压陷阻力的能耗机理进行研究,得到输送带在通过托辊时的压陷阻力系数及压陷阻力。在此基础上推导输送带张力与悬垂度的数学模型,对提高带式输送机计量精度有重要意义。
Many factors influence the accuracy of dynamic weighing belt conveyor, such as the tension by the viscoelasticity of the conveyor belt and resistance, etc. Based on consumption theory of the viscoelastic materials under the dynamic load power, conveyor belt of the sag resistance energy consumption mechanism be studied and derived, getting in sag resistance coefficient and sag resistance formula through the and material weight gotten. roller conveyor belt. Mathematical model of conveyor belt tension, hanging degrees was to get. Finally material weight detection method considering sag resistance was
