Modal Analysis and Structural Optimization of Rotary Flushing Fixture for Arc Discharge Machining
摘要
Abstract
Based on the theory of arcing controlling with the high-speed inner flushing flow fluid forming while machining,the rotary flushing fixture is designed.Furthermore,the dynamic characteristics of the rotary flushing fixture have the significant effect on the machining performance of the arc discharge machining.Therefore,the modal simulation analysis is conducted to explore the vibrant performance of the flushing fixture by a finite element analysis software ANSYS.The simulation results show that the vibration in some directions of the flushing rotary fixture would occur violently while machining,which results in large elastically deformation parts.The simulation analysis results show that the deformation of the elastic parts could be decreased by adopting the different material properties and geometric model,from which the structure optimization of the rotary flushing fixture could be realized.关键词
