Study on Dynamic Design Technique of Machine Tools Structure Based on Energy Balance

摘要

The energy balance of system is one of the basis for the dynamic design of machine structure. The paper applied finite element technique to machine dynamic design based on the energy balance, in view of finite element model of machine dynamics structure, mean squared deviations of various energy distribution were put forward to quantitatively describe the structural dynamic characteristics, and the technique was applied to the structural dynamic characteristics analysis of a surface grinder, the weak link of the grinding machine structure was found, which had instruction function for structure optimization of the grinding machine. The result proved this structure dynamics design technique had obviously superiority.
