目的建立支持虚拟操作分析的航天员三维人体模型。方法研究了层次化、关节化和参数化人体建模方法;通过CATIA软件建立人体骨骼层、皮肤层和服饰层静态模型,并将其导入到JACK环境当中进行关联处理,赋予人体关节运动特性。结果生成了可根据百分位和各体段参数进行调整的航天员模型,并实现了姿态仿真。结论建立的航天员人体模型具有几何外观特性和基本动力学特性,结合JACK软件环境,可以实现航天操作的可视性、可达性、疲劳度等分析。
Objective To establish an astronaut three-dimensional human body model that supports the analysis of virtual operations. Methods The hierarchical, joint and parameterized human modeling methods were studied. The static model of the human skeletal, dermal and apparel layers was established by CATIA software and imported into the JACK environment for correlation processing, giving the human joint movement characteristics. Results The astronaut model that can be adjusted according to the percentile and the parameters of each body segment was generated and the attitude simulation was realized. Conclusion The astronaut mannequin has the geometric appearance and the basic dynamic characteristics. Combined with the JACK software environment, the aeronautical operation visibility, reachability and fatigue degree can be analyzed.
