| Summary: | 碩士 === 義守大學 === 機械與自動化工程學系碩士班 === 94 === The purpose of this research is to apply an electromagnetic-driven clamping linkage unit on the micro-injection molding machine. The major design of the unit is referred to a patent , “linkage type mold clamping device driven by electromagnetic force”, and a fourbar linkage with two sliders has been utilized as the clamping linkage unit. Two types of analysis of the clamping linkage unit are expected to be drawn from this research: the kinematic analysis and the dynamic analysis. The kinematic analysis is able to compute the positions of the moving links of the clamping linkage unit and to obtain the motion characteristics such as speeds and accelerations. The other analysis, the dynamic analysis which is based on Newton''s second law of motion, the force applied on a body is proportional to the resulted acceleration of the body, is able to calculate how much force will be needed to drive the clamping linkage unit. The step followed is to measure the electromagnetic forces by experimental method and by FEM software(FEMLAB) simulation. The results from the measurements are used to conduct electromagnetic force analysis. By doing so, the applicability of the clamping linkage unit driven by electromagnetic force can be evaluated as a result of combining the outcome of the two procedures mentioned above.
