而虛擬工具機模型之準確度則為此技術之重要根基,此模型可大致分為結構模型及伺服控制模型,本文針對整機結構有限元素模型之準確度進行探討,然而在CAE技術中因為在工程上實際結構體非常複雜,若要以理論分析有相當大的難度,因此必須以數值分析方法解析,而在結構模擬分析中又以有限元素法(Finite Element Analysis, FEA)最廣為使用。為了能讓結構模型與實際結構更貼近且具合理性,本文分別對腳座及進給系統進行靜剛性實驗、建立數位模型,並配合實驗模態分析(Experimental Modal Analysis, EMA)以鑑別虛擬工具機數位模型中的影響關鍵,也就是模態參數,包含模態頻率、模態振型、阻尼比,並以變換機台各種位置的動態響應對此數位模型做驗證,最後建立一流程以此模型分析預測實驗機台的設計剛性及動態響應。

The position of the machine tools brand in the international market has almost been developed. Switzerland, Japan, Italy, Germany and other countries have stably occupied the high-end market, and the position that high price–performance ratio of Taiwan's machine tools is also facing the replacement by emerging countries such as China. Therefore, entering the high-end market is an imperative goal for Taiwan.
Although the development of Taiwan's machine tool industry is mature, most of the companies that produce it are based on the rules of thumb to develop and manufacture new machine tools. In recent years, domestic and foreign scholars have devoted themselves to the development of virtual machine tools to reduce the cost and time of research and development.
The accuracy of the virtual machine tool model is an important foundation for this technology. This model can be roughly divided into a structural model and a servo control model. The accuracy of the finite element model of the complete machine tool is discussed in this paper. However, in CAE technology, because the actual structure is very complicated in engineering, it will be quite difficult to be analyzed by theory , it must be analyzed by numerical analysis. In the structural simulation analysis, the Finite Element Method (FEA) is the most widely used.
In order to make the structural model and the actual structure closer and more reasonable, this paper conducts static rigidity experiments on the foot and feed system, and establishes a digital model. Experimental Modal Analysis (EMA) is used to identify the key influences in the virtual machine tool digital model, that is, the modal parameters, including the modal frequency, mode shape and damping ratio, Then, by changing the various positions of the machine, and measuring its dynamic response to verify the digital model. Finally, a process is established to analyze and predict the design rigidity and dynamic response of the experimental machine.
