摘　　要：研究了锻件的黏塑性特性,建立了锻件的弹黏塑性模型及本构关系,并以此为基础建立液压模锻锤动态力学模型,求解了打击力及基础振动数学解析式,进而进行仿真研究并给以实验验证。研究表明:本文建立的模型可应用于液压锤的设计中。The viscoplastic behavior of the forging was studied, its elastic-viscoplastic model was built and its constitutive relation was presented. Based on these a dynamic model was established for the hydraulic forging. The hammer hitting power was calculated, and the mathematical expression for the hammer formdation vibration was solved. The simulation research was performed and the results were verified by experiments. It was concluded that the established model can be used in the engineering design of the hydranlic forging hammer.
