在制造过程中不可避免地会引入几何变化,因此可以在每个制造的人工制品上观察到。尽管人们普遍认为这些零件偏差会明显影响机械装配的功能和质量,但大多数虚拟产品验证活动仍然依赖于对标称产品几何形状的建模和分析,而没有考虑此类几何零件偏差。本文的目的是突出的几何变化建模方法的虚拟产品实现的现状,并开拓未来的挑战,在这一领域。为此目的,不同的几何表示方案,这是目前使用的虚拟产品实现过程中,进行了讨论。此外,它们与各种虚拟产品实现活动相关联,并突出了改进其使用和交流的潜力。的贡献的新奇,可以发现在全面审查的方法几何变化建模,他们的位置到一个不断变化的虚拟产品开发环境,并阐述了未来的研究在这一领域的挑战。
Geometrical variations are inevitably introduced during manufacturing and can thus be observed on every manufactured artefact. Although it is widely acknowledged that these part deviations distinctly affect the function and quality of mechanical assemblies, the majority of virtual product validation activities still rely on the modelling and analysis of the nominal product geometry without considering such geometrical part deviations.In order to overcome this shortcoming, the aim of this paper is to highlight the current status of geometrical variations modelling approaches for virtual product realization and to carve out future challenges in this domain. For this purpose, different geometry representation schemes, which are nowadays used during virtual product realization, are discussed. Furthermore, they are linked to the various virtual product realization activities and potentials for improvements for their use and exchange are highlighted. The novelty of the contribution can be found in the comprehensive review of approaches for geometrical variations modelling, their placement into a changing virtual product development landscape, and the exposition of elaborated challenges for future research in this domain.
