摘　　要：采用合理的摩擦模型、测定准确的摩擦参数与恰当的评估体积成形摩擦条件对体积成形工艺路径的制定和优化十分重要。由于金属体积成形过程中的高压、高温、工艺参数多样性及其之间复杂的非线性关系,使得体积成形中工件和模具之间接触面上的摩擦描述与评估较为困难。为了适用不同工艺条件,不断发展和改进多种形式的摩擦模型与摩擦测试试验,从摩擦模型、摩擦评估测试方法、不同模型中摩擦参数的对应关系等方面评述了金属体积成形摩擦的描述与评估研究进展,详细阐述了几种适用性强、具有应用前景的摩擦模型结构形式、数值化特征、适用范围与摩擦参数测定方法。Adopting a reasonable friction model,measuring accurate friction parameters and properly evaluating the friction conditions of bulk forming are very important for the formulation and optimization of metal bulk forming process path,and due to the high pressure,high temperature,diversity of process parameters and the complex non-linear relationships among them in the metal bulk forming process,it is difficult to describe and evaluate the friction on the contact surface between workpiece and mold in the bulk forming process.Therefore,in order to adapt to different process conditions,continuously develop and improve various forms of friction models and friction test testing,the research progresses of description and evaluation for friction during the metal bulk forming was reviewed from some aspects such as friction model,friction evaluation test method and the corresponding relationship of friction parameters in different models,and the structure type,numerical characteristics,application scope and friction parameters measurement methods of several friction models with strong applicability and application prospects were elaborated in detail.
