The Finite Element Analysis And Optimization Of 6000 Disc PelletizeËŠs Disk

Pelletize is the essential equipment for the production of pellets, and its reliability and stability are closely related to the of pellet production. At the national level, due to pelletizing quality of disc pelletize is relatively good and the size is uniform, so it is widely used in pellet production. At present, on the design of disc pelletize research lags behind the application, and lacks of design theory and methods. To ensure the stable operation of disc pelletize, in the actual design, tend to increase size of main parts by experience, and this creates redundancy increasing, weight increasing, efficiency of the equipment dropping, and manufacturing costs make higher. This thesis chooses Φ6000 disc pelletize plate to be study subject. Through the finite element analysis and optimal design, the plate is detailedly simulated under the complex condition, and based on the simulation improving the design scheme, in order to reduce the weight of the equipment.Disc pelletize includes disk, support frame, scrapers, and drive system. Disk has the regular shape, and poor working conditions, and its force is complicated. This thesis chosed the finite element analysis software ANSYS for platform to built the parametric model of disc body, and used free network grid divided way on model points network, and get the finite element analysis model of disc body; based on establishing disc body material load calculation method, and combined raw materials components of making rall, and work dip, and getted the maximum load workers condition of this machine; calculated out the maximum load work condition, and imposed the load and constraint conditions to the finite element analysis model for solution operation of the static strength, and obtained stress, strain, and displacement images under maximum load conditions; and on this basis, setted up two strength condition to optimize the structure of disk to obtain under design size of components.Through analysis and optimal design, this project completed static strength analysis of the disk under the maximum load condition, and determined actual working condition, and through optimization obtained design programs under two structure strength of plate. Analysis results clearly reveal the force and deformation and stress distribution of disk under the actual working conditions, for the disk design providing a true and valid data; the results presented two components designation size, and provided a reference for design, and effectively reducing body weight. Project research results to improve disk design quality and lower weight, and lower manufacturing costs.
