中文摘要：介绍了金属薄板振动渐进成形的工作原理，分析了成形工具的参数间的关系，得出了金属薄板变形区所需变形力的表达式。通过Matlab软件计算，对成形过程中金属薄板被施加振动载荷和不施加振动载荷的变形区所需变形力进行比较，在施加了振动频率 10 Hz和振幅 0.05 mm的振动载荷情况下变形力可降低26.3%，从而可缩小成形工具的径向尺寸，提高成形零件的尺寸精度，降低加工能耗。
英文摘要：The work principle of incremental precision forming with vibration was introduced. The relationship of some parameters of forming tool was analyzed, so the expression of the deformation force in the deforming zone of sheet metal was deduced. Based on the calculation with Matlab software, the deformation forces in the deforming zone of sheet metal during forming were compared with and without pressure in vibration. The deformation force can be reduced by 26.3% when the tool's vibration frequency is 10 Hz and the amplitude is 0.05 mm, then the tool can be made smaller, the workpiece precision can improve, and the energy consumption may reduce.
