摘　　要：打击力是液压模锻锤的重要参数,以往的研究往往不考虑或简略考虑锻件的影响。该文从锻件的弹粘塑性特性出发,建立了锻件的弹粘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,求解出打击力数学解析式,进行了仿真研究,并给以实验验证。研究表明,文章建立的模型可应用于液压锤的设计,具有实际意义。Hitting is an important parameter of the hydraulic forging hammer, of which the effects on the forging was not considered or neglected in the research previously. This article based on the elastic-viscoplastic behavior of the forging, presented its elastic-viscoplastic model and its own constitutive relation, with these established the dynamic mechanics model of the hydraulic forging hammer, and also calculated the mathematics analytic equation of the hitting power. Furthermore indicated the simulation research and also proved the results by experiments. The research showed that the model which was established in this paper can be used in the design of hydraulic hammer, and also has its own meaning actually.
