Static and modal analysis of circular forming tools based on ANSYS

Based on analysis platform of ANSYS,under different load conditions,the distribution of the maximum deformation and maximum stress for circular formed turning tools designed is analyzed,and thus the adequacy of the tool strength is determined;under different constraints,the changes of natural frequency and vibration mode for the tool are analyzed,which provide a theoretical basis for the evaluation of the tool dynamic characteristics.Through analyzing steady-state structure,it shows that the distributions of the tool deformation and stress are smaller under maximum load,which meet the strength requirements;modal analysis shows a higher natural frequency of the tool,and the external impact frequency is lower than the natural frequency,the rigidity of the tool is sufficient,thus resonance is not easy to occur.That is to say the dynamic characteristics of the tool meet the processing requirements.
