Summary: | 碩士 === 國立虎尾科技大學 === 創意工程與精密科技研究所 === 99 === 3C products in the current manufacturing industry is very competitive, the related industry is no matter a manufacturing and process, pack, sell, have a count for much position and have the big competition the rate in the society in present, the main factor of each other competition ability difference lies in how to let the quality rising of product and reduce cost and service life increment. For 3C products meet the required demand is light, thin, short, small, On its development of aluminum alloy, owning several advantages be like the quantities are light and spread hot effective, quantity balanced, appearance variety, the safe performance is excellent and recall cost is low for the aluminum metal alloy, various needs that almost match a 3C product. These factors, especially the case of product in the application of 3C product, the old type of compound material and over-weight steel material of have already gradually replaced, be developed and application because of the advantage of aluminum metal alloy.
This focus is to test the performance of the product, And the number of simulated data as well as product design, mold design and manufacturing of important data; first , carries on the strength test of product by the method of finite element, with drop test by method of explicit and the time step control is through the element of the method of finite in order product , get the result by many experiments of set of drop test, the position of Max strain, Max stress, Max shear stress and distribution of pressure are not identical by different thickness, and the drop test is in the same enactment, produce a broken related data by the drop test of 0.75 mm thickness, therefore the condition improving a product obtains through that emulation. Another, the theories by the Topology optimization of the premise to doesn''t influence strength to the product by this research, to carry on partial optimization of the product, be able to tell as a result for the emulation from the shape optimization, the result of optimization is doesn''t decided by the amount of thickness, and the optimization district by the software, the modification in order to carried on product model, and carry on a drop test of the product again, confirm of can use of product by shape optimization. Then, carry on the simulation of forging of phone cases application of emulation software by mechanical theory of the deformation of rigid-plastic by method of finite element, get the parameter of the forming force use to product''s manufacturing, got a information for the aluminum metal alloy 6061 through this emulation, need of take forming force more low because the temperature high, and oppositely of the data in formability getting better and better.
Will above the data of Obtained, be applied to the design and manufacturing of dies, decide related main factor of shape, size and material, can be economical experiment cost and development cost by the step, be used for the of produce and applied to dies, can get the product of assurance features , strength enough and the quantity is lightweight, and can carry out to confirm of simulated data in confirm in advance, reach a purpose at the meaningless test and the consumption, reach the effect of reduce cost and raise a production efficiency.
