弹射座椅的静态舒适性仿真

Simulation of ejection seat's static amenity

针对弹射座椅舒适性存在的不足,基于Poser软件,首先以中国男性飞行员尺寸为依据,建立了三维静态人体模型,保证了人体主要部位尺寸的准确性;然后把AutoCAD中的弹射座椅导入3Dmax软件中,结合飞机座舱的几何尺寸及各操纵机构的几何尺寸,建立弹射座椅-座舱操纵机构模型.最后把该模型导入Poser软件中,利用人机工效学的相关理论,建立弹射座椅-飞行员-座舱操纵机构系统平台模型.在系统平台中对飞行员进行操纵仿真和分析,讨论了影响弹射座椅舒适性的因素并提出了优化设计方法.由于系统平台中参数的准确性和可调节性,提高了弹射座椅舒适性研究的标准化和通用化程度.

Aiming at the problems in the amenity of the ejection seat,based on the Poser software,the 3D static manikins of chinese male pilots was established, insuring the veracity of the main parts of the human body. Secondly,the ejection seat model was imported to 3Dmax,and established a ejection seat-control equipment model, according to geometry size of plane cabin and control equipment. At last,a ejection seat-pilot-control equipment system model was established by utilizing the theory means of ergonomics. By taking a move-ment simulation and analysis for the pilot on the platform, some amenity factors was discussed and the optimization designing method was provided. The platform can increase the degree of standardization and generalization of the amenity study, because of the veracity and adjustment of the parameter.
