提供全套毕业论文图纸，欢迎咨询摘要数控铣床日益向高速度、高精度和高刚度的方向进展，其机构日趋复杂，对其工作性能的要求越来越高。而发达国家在进出口技术含量高的五轴联动加工中心方面，对我国进行限制。所以，我国就必须自主开发。虚拟制造技术的进展应用，为开发讨论高技术数控机床产品提供了技术手段。本科题的主要任务是在设计阶段采纳有限元法完成基础件（底座、工作台、滑枕、立柱）及整机的虚拟动力学分析。其虚拟动力学讨论包含两个方面：固有振动特性分析和响应特性分析。对基础件（底座、工作台、滑枕、立柱）及整机进行了固有振动特性分析，得出了相应的固有频率和振型，通过振型的动画显示，形象而逼真地描述各模态的振动过程。对滑枕进行了响应特性分析，得出了主轴在工作转速下的响应位移，并绘出了主轴在一系列频率下的响应位移对频率的曲线。本课题的讨论，为设计高性能的基础件（底座、工作台、滑枕、立柱）及整机提供了可靠的理论依据，缩短了产品的开发周期，降低了开发成本，其中的分析方法易于推广到其它各类机床的开发讨论中，故本课题的讨论方法及结论具有广泛的工程意义。ABSTRACTThe milling machine is developing towards high speed, high precision and high rigidity, its organization is becoming more complex, the need of its work performance is becoming more. For the developed countries restrict our country in importing the NC machine with 5-axes linkage, we should do it by ourself. The development and appliance of the VMT provide the technical measurement in exploiting the NC machine tool of the high technology. The main task of this study is the accomplishment of the virtual dynamics of the basic parts including worktable、base、slider and the whole machine by means of the finite element analysis. The virtual dynamics research include two sides: the analysis of the inherent libration speciality and the analysis of the response speciality.The analysis of the inherent libration speciality of the worktable 、 base 、 slider and the whole machine oth the system is done to get t...
