How to analyze the deformation of the conveyor belt by ADAMS

Assuming that the rubber conveyor belt  does not deform during its working, the motion equation of the test section of the conveyor belt can be defined according to the trajectory of the rigid test section. Define the system coordinates of the belt conveyor model at the center of the collection of the virtual prototype, and calculate the movement trajectory of the point of mass at the center of the test section of the conveyor belt carrying section as the starting point. The trajectory formed afterwards.

In order to perform numerical analysis on the kinematics and dynamics characteristics of the belt rubber conveyor belt, it is necessary to select the test part units at several typical positions on the conveyor belt as the analysis reference point: mainly the centroid point of the test part in the center of the load-bearing section of the belt conveyor , Drive the centroid point of the test part where the roller is just in contact with the rubber conveyor belt, and change to the centroid point of the test part where the roller is just in contact with the conveyor belt, a total of three points.

Under stable conditions, the belt speed of the conveyor belt is 5m/s, and the operation cycle of the entire virtual prototype system of the belt conveyor is 2.5024s. However, in fact, the initial start-up phase has a process of accelerating the drive motor to ensure a complete simulation of the simulated belt The motion simulation effect of the conveyor system must calculate the start-up acceleration time of the belt conveyor in the cycle. In order to more completely observe the operation of the belt conveyor, the system simulation time is set to 10s, the time step is set to 100 steps, and then click the simulation button to perform system simulation.

After the complete dynamic model of the conveyor belt is completed, the dynamic transportation characteristics of the belt conveyor can be simulated according to the set drive conveyor pulley, and the corresponding conveyor belt tension can be seen intuitively from the simulation result diagram. The gradual change causes the conveyor belt to deform. Under different conveying working conditions, the ADAMS powerful graphics processing function can be used to extract the motion parameters such as speed, acceleration and displacement of any point on the conveyor belt at any time. Through these dynamic characteristics parameters, the rubber conveyor belt and roller can be further analyzed. Stress conditions to verify the rationality of the design of each component. By analyzing the speed and acceleration to determine the smoothness of the starting and braking process of the belt conveyor drive pulley and the rationality of the optional device, by analyzing the displacement of any point on the conveyor belt, it can be obtained whether the conveyor belt slips and deviates.

The viscoelasticity and conveyor belt itself will cause the actual movement displacement of each point of the rubber conveyor belt to be very different from the movement displacement of the assumed fully rigid test part. You can compare the displacement difference between the two Analyze the deformation of the conveyor belt. Based on the above ideas, the motion simulation analysis of the virtual prototype system of the belt conveyor is performed, and the parameters such as the contact stiffness, damping coefficient, friction coefficient and penetration value of the contact surface when the roller and the conveyor belt are fully set are set.
