主　　题：Pipe conveyor FEM Normal force Sag resistance 

摘      要：Pipe belt conveyor is a new type of environmentally friendly and efficient bulk conveying *** the design of the roller,the belt and the driving motor of pipe belt conveyor,the sag resistance is a key ***,the normal force between the conveyor belt and the roller group is the other important factor need be considered and has a great influence on the sag *** paper analyzes a pipe belt conveyor with a diameter of 150 mm to study the calculation method of normal *** the relationship between the normal force and the sag resistance is ***,the normal force is decomposed into three components related to the forming force of belt,material gravity and belt *** it can be expressed as a linear combination of these three quantities,and the coefficients of each component are obtained based on the dynamic analysis of *** results show that the coefficient is mainly affected by the material filling rate,and is almost not affected by the distance between the rollers and the density of the *** calculation method of the normal force is eventually ***,the normal force in the case of different material filling rates is tested by experiments,and the calculation method of the normal force is ***,the variation law of the sag resistance in the case of different roller group spacing and material filling rate is studied by the dynamic *** is found that the roller group spacing and material filling rate affects the sag resistance by changing the normal *** is a power function relationship between the sag resistance and the normal *** the case of different roller group spacing and material filling rate,the relationship among the sag resistance and the normal force remains *** study results are of great significance to the design of pipe belt conveyor.
