Currently, expectations of shorter time-to-market and improved product performance are placing greater demands on manufacturing companies. However, the optimization and redesign work between the design stage and the prototype design and manufacturing stage in the traditional product development process lengthens the required product development cycle time (which lasts up to several years in extreme cases). The manufacturing phase for the physical prototype of the product is especially time-consuming and costly. The above reasons make the common product development process increasingly unable to meet the demands of market needs. Motivated by this need, the digital twin (DT)-driven manufacturing equipment (ME) development method is studied in this paper. This method contains three main core elements of the design method based on axiomatic design (AD) theory, the construction of DT models related to ME development, and DT-based validation analysis. The advantage of this method is that it can incorporate the physical prototype manufacturing stage into the digital space with the high-fidelity model provided by the DT technology, which ensures the confidentiality of the design scheme validation while freeing it from the physical prototype stage. This avoids the cost of physical prototyping, shortens the product development cycle, and improves the efficiency of new ME development. At the end of this paper, a case study of the development of a virtual machining dynamic performance test bench (VM-TB) is carried out to show the implementation flow of this proposed method, and its operability and effectiveness are verified.

目前，对缩短上市时间和提高产品性能的期望对制造公司提出了更高的要求。然而，传统产品开发过程中设计阶段和原型设计制造阶段之间的优化和再设计工作延长了所需的产品开发周期（极端情况下长达数年）。产品物理原型的制造阶段尤其耗时且成本高昂。以上原因使得通用的产品开发流程越来越不能满足市场需求的要求。在这种需求的推动下，本文研究了数字孪生 (DT) 驱动的制造设备 (ME) 开发方法。该方法包含基于公理化设计（AD）理论的设计方法、ME开发相关DT模型的构建、基于DT的验证分析三大核心要素。该方法的优势在于利用DT技术提供的高保真模型，将物理样机制造阶段纳入数字空间，在将设计方案验证从物理样机阶段解放出来的同时，保证了设计方案验证的保密性。这避免了物理原型制作的成本，缩短了产品开发周期，并提高了新 ME 开发的效率。在本文的最后，进行了虚拟加工动态性能试验台（VM-TB）开发的案例研究，以展示该方法的实现流程，
