【摘要】 综述金属加工过程中颤振控制的研究概况和进展。根据颤振发生的原因和特点,把对于颤振的控制策略分为对于机床结构的控制和对于切削过程的控制,对于机床结构的控制又进一步分为被动控制、半主动控制和主动控制,总结归纳了前人的研究成果,梳理当前的研究进展。切削颤振控制技术在理论方面受到的制约仍然存在,一些新的技术和新的材料的出现促进颤振控制研究的快速发展,但同时它们本身的发展还面临的一些亟待突破的问题,对这些问题进行分析。随着智能材料和新的控制理论和思想的发展,除传统的控制方法不断得到改进和发展之外,基于智能材料的各种智能控制技术、时滞控制器,以及针对切削过程的非线性、时变性的模糊控制,神经网络等智能控制算法的应用等一些新的控制方法和趋势逐渐也出现在颤振控制的研究中,对它们的研究状况进行分析和展望。最后对切削颤振控制技术发展的总体状况进行评述。更多还原

【Abstract】 Literature on the suppression of chatter induced in machining process is reviewed.On account of their resources and features,the strategies are divided into two categories,i.e.the control of machine tool structure and the control of cutting process,and the former is further divided into active control,semi-active control and passive control methods.The key achievements under each category are summarized and the recent advances are introduced.There still exist theoretical constraints related to cutting chatter control.The emergence of some new techniques and new materials promote the rapid development of this subject,whereas those ideas and materials themselves also face a number of development obstacles urgently needing breaking through.The developing methods of intelligent control based on smart materials and intelligent control schemes such as fuzzy control and artificial neural networks,are also denoted considering the time-varying and nonlinear features of the machining process.The general development status is evaluated in the conclusion.更多还原
