AbstractWith the industry of rubber and plastic prospering, there is wider and wider application of rubber and plastic products. Besides, the requirements for such products are higher and higher and the standards for totally enclosed mixing mill has become more and more strict. This treatise makes systematic designs and analysis of the major reductor, rotor, structure, cooling methods and turbine reverser of the totally enclosed mixing mill on the basis of referring to a mass of both domestic and foreign literature concerning the principle of mixing refining and related experiments. The treatise accomplishes the 3-D modeling and assembling of the totoal enclosed mixing mill using UG, makes finite element analysis of rotors of key parts, makes optimizational design of parameters of velocity ratio gears before and after the mixing with the MATLAB software, writes optimizational programs using the MATLAB language, calculates, analyse and seek the best result with MATLAB optimizational tool box, analyse the optimizational result from a realistic angle and at last, makes emulational analysis of the total enclosed mixing mill and get the emulation result to test and verify the words: total enclosed mixing mill, 3-D modeling, finite element analysis, optimizational design, emulational analysis校过一遍,仅供参考,希望有用。
