The Three-Dimensional Modeling And Dynamic Simulation Of Belt Conveyor Based On ADAMS

As a continuous conveyor driven by mechanical friction, belt conveyors are used to transport all kinds of materials, its operation is smooth and reliable while costs low energy, the driving power is small, short or long transmission distance is supposed, line layout flexibility,what is more,it can be adapted various work environments, is easy to install and maintain, easily automated and centralized control, finally,it is widely used in various industries. With the level of technology advances, society increasingly demanding conveyors, belt conveyors began to large, diversified, intelligent, green development, the conveyor industry emphasis on increasing experimental study high, investment is growing.However, based on the statics of the rigid nature of the material and the assumption of traditional design methods, it can not truly reflect the viscoelastic properties of the material due to the belt exhibit specific dynamics performance,running the whole process suffered dynamic tension, thus obtained design results were not accurate, so that the conveyor there are many security risks in the long run work cycle, especially in starting and braking phase, the higher the probability of failure. Therefore, the dynamic characteristics of the conveyor to explore research, the key factor in my problem, take effective measures against key to help improve the reliability of the conveyor speed smooth running, to find a suitable design redundancy interval so that the final design results more reliable and efficient.This paper describes the theoretical basis of ADAMS dynamics analysis,and multi-body dynamics, soft body dynamics equations of motion. Combined with the actual operation of the belt conveyor, starting from the mechanical properties of the belt on the belt conveyor dynamic characteristics were analyzed according to the vibration theory, determine the kinetic equation of longitudinal micro vibration conveyor Yuan Yuan, the lateral vibration. Using vi Voigt viscoelastic model to build the machine, the machine launched kinetic equation for the belt conveyor simulation analysis provides a theoretical basis.According DTIIA Belt Conveyor Design Manual and the actual application needs, through the SolidWorks 3D modeling software for each belt conveyor parts create the model geometry, assemble parts into components and then assembled into a belt conveyor machine model. Because of the larger machine models will be imported after the simplified mechanical system dynamics analysis software ADAMS, the start of the conveyor, free parking and emergency braking, smooth-running condition simulation analysis, the conveyor belt at any point in dynamic tension force suffered under the circumstances described above, acceleration, displacement generated by the velocity versus time graph of a function. Where to get the desired results of the simulation, there are two main points: a flexible conveyor belt model and simulation to achieve.The paper generated MNF modal neutral file by ANSYS, ADAMS obtained introducing flexible conveyor model. Simulation realize you need to set reasonable steps to ensure that the simulation results meet the needs of the data obtained. Analysis of the data chart summarizes the variation obtained,according to the variation of the key points, the use of the resulting data, the traditional design methods to optimize the results obtained lightweight design.
