由于大型产品装配过程复杂、操作难度高，因此虚拟装配的应用具有重要意义和实际应用价值。提出了面向大型复杂产品的虚拟装配关键技术，分析了大型复杂产品虚拟装配的组织形式、人员参与、工艺规划与优化等装配特点。首先，建立了一种新的考虑人类活动的虚拟环境系统。其次，实现了从CAD到VA系统的数据集成，并应用基于虚拟现实(VR)和智能算法的混合方法对装配工艺规划进行了优化和评价。此外，还实现了装配文档生成和装配工人的Web培训。最后，给出了一个复杂产品VA系统的应用案例，并指出了需要进一步研究的问题。
Due to complex process and high difficult operation for large-scale products assembly, the application of virtual assembly (VA) has an important significance and also an actual value. In this paper the key techniques of VA for large-scale complex products are proposed, and their assembly characteristics (such as their organization form, human participation, process planning and optimization and so on) are analyzed. First, a new virtual environment (VE) system considering human activities is set up. Second, an integration approach is realized to transform data from CAD to VA system, and a hybrid method on the basis of virtual reality (VR) and intelligent algorithm is applied to optimize and evaluate assembly process planning. Moreover, assembly documents generation and Web training for assembly workers are implemented. Finally, an application case of the VA system for a complex product is given, and further work is pointed out.
