碩士 === 國立交通大學 === 機械工程系 === 90 === The first objective of this research is to build a finite element analysis model for tube spinning by the LS-DYNA analysis software. The major concern is to choose mass scaling factor and time step for this model to enhance the analysis efficiency. The other objective of this research is to find the effects of parameters on tube spinning and to obtain the notable parameters by the method of Genichi Taguchi quality engineering parameter design. The result of optimum parameters for the model will minimize the resulting contact force and eliminate the phenomena of vibration which is caused by the unbalanced contact force of rollers of the tube spinning machine.
