碩士 === 國立中正大學 === 機械工程學系暨研究所 === 103 === This study using topology optimization applied to the structural design of the machine tool design process, and then use finite element analysis software to the machine and each component of static and dynamic characteristics under various motion states. In addition to bear the weight of each part of the machine, the machine tool structure also required to withstand the forces caused by the cutting, however, grinding force is very complex, therefore, one of the major goal for this study is to identify the maximum cutting force used for design. The purpose of this study is using topology optimization technique to design the characteristic of machine tool structure involved lightweight and high stiffness. First, build a reliable machine tool finite element model which is validated by modal testing. And considering the static/dynamic stiffness in different spindle location, mass point, weight, displacement of critical point and practical casting condition in the topology optimization technique to achieve the optimization goal of lightweight and high stiffness in the machine tool structure. Finally, compare the optimization results with original FEM model for validating the effectively of the optimization process in this study.
