【摘要】 随着科学技术的飞速发展和市场竞争的日趋激烈，用户对产品的性价比要求越来越高，对产品的供货周期要求越来越短。若想在竞争激烈的市场中占有一席之地，只依靠传统的基于类比、经验和试验的设计方法和设计手段已经捉襟见肘，必须采用先进的现代设计理论和设计方法。随着计算技术的飞速发展，经典力学和计算技术相结合的计算多体系统动力学应运而生，为机械系统的动力学分析和仿真提供了理论支撑。在对云南铜业股份有限公司和甘肃金川集团有限公司的铜电解阳极板准备机组的实地调研过程中，发现国产的机组与进口的机组存在着明显的差距。为了对引进的技术和设备进行消化吸收再创新，本文以金川公司引进的芬兰奥托昆普的铜电解阳极板准备机组的铣耳机夹持机构为研究对象，以多刚体系统动力学为理论基础，以机械系统动力学自动分析软件ADAMS为软件平台，对该夹持机构进行系统动力学的分析与仿真，以期该夹持机构在国产化研制的过程中实现基于虚拟样机技术的产品设计，同时也为同类产品的研究开发提供参考模式。本文通过对铜阳极板挂耳铣削时的铣削加工过程进行分析，运用铣削加工的相关知识，计算了铣削力的大小，并运用有限元分析软件ANSYS，分析了铜阳极板在挂耳铣削时的受力情况，得出了所需的夹持机构的最大夹紧力的大小。通过对铜阳极板铣耳机夹持机构的工作原理进行分析，运用多刚体系统动力学的相关理论，对该机构进行了系统运动学的分析，比较系统地建立了三种典型运动副的运动学方程；又对该机构进行了系统动力学的分析，比较全面地分析了两种典型运动副处的广义力。通过运用ADAMS／Exchange将三维建模软件Unigraphics中创建的夹持机构的实体模型导入到ADAMS中，添加适当的约束和载荷，创建了该夹持机构的虚拟样机。通过对虚拟样机进行运动学仿真和优化，验证了该夹持机构运动的可行性和可靠性；通过对虚拟样机进行逆向动力学的仿真分析，得到了该夹持机构在运动过程中的一些重要力学数据，从而为该夹持机构的动力设计和进一步优化提供了力学依据，提出了一些改进的建议。更多还原

【Abstract】 Along with the rapid development of science and technology and the increasingintensity of market competition, users have been demanding higher and higherperformance-cost ratio of product, shorter and shorter cycle time of goods supply. Forthe intense competition in marketplace, only relying on traditional design method andmeans which based on analogy, experience and attempt has already too manyproblems to tackle, had to adopt the advanced modern design theory and designmethods. Along with the rapid development of calculation technology, thecomputational dynamics of multi-body systems unified by the classical mechanicsand the computational technology has emerged, which has provided the theoreticalsupport for the analysis and the simulation of mechanical system dynamics.By investigation of copper anode plate ready units in Yunnan Copper Co. andJinchuan Group Ltd. the crew have discovered the obvious disparity betweenhomemade and imported machine. In order to carry on the digestion and absorption tothe introduction technology and the equipment to innovate again, Researched on thecoupler in the lug milling unit of copper anode plate ready unit introduced fromOutokumpu by the Jinchuan company, based on the theoretical basis of themulti-body system dynamics, in software platform of the mechanical systemdynamics automatic analysis software-ADAMS, this article has carried on the systemdynamics analysis and simulation to the coupler, so as to realize product design basedon the virtual prototype technology in the domestic development process of product,also, a reference pattern for the research and development of similar product has beenprovided.Based on the analysis of milling processing process of the lug linked to thecopper anode plate, by use of milling processing knowledge, this article hascalculated the size of milling strength, and has analyzed the milling force of copperanodes plate when lug in the milling situation by use of the finite element analysissoftware-ANSYS, and then has obtained the largest clamping force of the coupler, byanalysis of the working principle of coupler in the lug milling unit of copper anodeplate, by use of the relevant theories of the multi-body dynamics, this article has carried on the system kinematics analysis to this mechanism, systematicallyestablished kinematics equation of three kind of typical campaign deputy, also, hascarried on the system dynamics analysis to this mechanism, a more comprehensiveanalysis of the DC power of the two typical of generalized movement has been carried.The entity model of the coupler created by the 3D modeling software-Unigraphicswas leaded into the ADAMS by ADAMS/Exchange, adding appropriate restraint andload, a virtual prototyping of the coupler has been created. Through carries on thekinematics simulation and the optimization to the virtual prototyping, the feasibilityand reliability of the motion of the coupler has been confirmed; Through carries onthe reversion dynamics simulation and analysis to the virtual prototyping, someimportant mechanical data of the coupler in the motion process have been obtained,which have provided mechanical basis for the power design and further optimize ofthe coupler, and some suggestions have been made for improvement.更多还原
