摘　　要：目的探讨一种用于舱外航天服视野设计和分析的虚拟视域仿真建模方法。方法利用Solidworks软件建立三维人体模型,在对软件进行二次开发的基础上,充分利用软件提供的聚光源特性,建立了模拟人眼视锥及人眼运动的仿真算法,从而在Solidworks软件中实现人穿着舱外服后的虚拟视域仿真分析。结果将所建立的模型用于舱外服视野分析,其结果与人-服试验过程视野工效测试结果相一致。结论该模型可应用于舱外航天服设计过程中,对于其它具有工效要求的产品设计具有参考意义。Objective To explore a virtual visual threshold modeling and simulation method for field of vision design and analysis in EVA spacesuit. Methods First, a 3D human model was constructed with Solidworks software. Then, on the basis of seeondary development of Solidworks, an algorithm for visual taper and eye movement simulation was established which takes full advantage of the spot light features of the software. Thus, the virtual visual threshold simulation for human with EVA spacesuit was realized in Solidworks soft- ware. Results The analysis of spacesuit vision field with constructed model was in consistent with the ergonom- ic results obtained during human-spacesuit tests. Conclusion The model can be used for spacesuit design and can provide references for other product design with ergonomics demands.
