| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 99 === The purpose of this research paper would be use the accelerometer , that will contain the Finite Element Model and software of Modes Analysis to research the machine structure , after studied this item that will got the some value of machine dynamic and static state include all the stress and influence where have to suffuse whole machine body. Also reference the analysis conclusion to improve machine structure design where have some defects; finally will obtain the optimum state of machine structure rigidity.
FEM that was normal and availability to analysis machine structure rigidity at present, the better when together doing Modes experiment in the meanwhile, to research some important spare parts such as spindle, tools magazine, column, ballscrew and table etc., that the vibration and noise phenomenon would be transformed and utilization Fourier wave transform model to study and analysis the strength relation between vibration, noise and all spare parts when the state will under different condition of cutting,. And utilizing this result of analyzing to got the various kinds of unfavorable factors of a precision and life-span of machines under processing of dynamic model, and also utilizing mathematics analyzing type of machines in order to setting up the prevent and early warning result of a parts state. Meantime make use of this reverse tactics way to get the optimization design of machine structure and specification selecting of every important spare parts, in order to reach to the goal of improve the precision and life lengthening of machines.
