基于相似理论的虚拟样机有效性的研究

Study on Virtual Prototyping Validity Based on Similarity Theory

从相似理论的角度 ,剖析了虚拟样机技术 ,认为在虚拟样机建模中存在着大量的相似问题 ;以相似理论为基础对虚拟样机可信度判定进行了深入研究 ,对虚拟样机和实际系统相似要素和两系统相似程度进行了量化 ,给出了系统相似度及相关的计算公式 ,并以立式行星磨虚拟样机为例 ,验证了上述方法的正确性。

Based on similarity theory, virtual prototyping technology is explained, and especially similarity in modeling of a virtual prototype is stated systematically. The determination of credibility of a virtual prototype is explored and similar units, system similarity are quantified. In the meantime, principles of constructing similar units and calculating formula of system similarity have been defined. The above idea has been successfully used in virtual prototyping design of a Vertical Planetary Mill.
