| 摘 要： | 振动切削的加载特定性决定了切削中应力波的产生，应力波传播对振动切削的微观机理产生重大影响。以振动切削中应力波产生及在切削区的传播为切入点，对内反射波，反射断裂及动态应力强度因子加以分析，并进行有限元仿真，解释了振动切削的能量作用集中，剪切角增大的实质。

| Abstract: | The specification of the vibration cutting loading is a decision factor for the generation of stress wave and the stress wave propagation has a significant impact on its micro-mechanism.Making the stress waves' generation in the cutting area of vibration cutting for entry point,the analysis of internal inflection wave,inflection fracture and dynamic stress intensity factor has been carried out,the simulation of vibration cutting has also been done by finite element method,the essential of energy concentrate... |
