Rolling System Of External Screw Skew Rolling Model And Numerically Analyze

Using self-boring grouted rock external screw bolt to build geotechnical anchor, is the key technique by which resolve the difficulty of the construction in complex geologic circumstances. And external screw steel tube rolling is the key equipment to manufacture finish rolling external screw steel tube. Deeply studying external screw steel tube rolling have important significance, to accelerate new-style technique of anchor quick development and carry out home-madeization of self-boring grouted rock external screw bolt.By analyzing the work's principle of external screw skew rolling, apply Solid Works and COSMOS to build three- dimensions solid model of rolling system of external screw skew rolling by the technique of character modeling, and to build the virtual assembly. Utilize COSMOS Motion to carry out the system dynamic simulation and animate. By means of the visual vivacious AVI movie, check the movement situation of components of the system, including their displacement, velocity, acceleration, acting force and reacting force, etc. Then lay out product's function, and exchange idea of designed.By studying the technique of Finite-element method, build valid scheme of numerical analogy. By constructing the three- dimensions solid model, loading, calculation, resolution and result's after-treatment, obtain the regular of parameter optimization of roller of external screw skew rolling. Based those work, achieve the facture of digital prototype of rolling system.The dissertation is better resolved the key technique of external screw skew rolling, and have the important guidance significance to their design and manufacture. Moreover the idea and means that external screw skew rolling is modeled, simulated,analyzed and made the digital prototype, have academic manufacture and practicality value to research and develop new machine system.
