Design and implementation of virtual maintenance training system based on Ngrain aviation equipment Li Hongpeng1a, Li Shu1b, Lv Yingjun2a, Wang Yuanda2c and Lin Jinqing 1a 1School of Aeronautics Science and Engineering of Beihang University, Beijing, China, 100191, 2Department of Vehicle & Engine, Aviation University of Airforce, Changchun, China, 130022 amartinelee@163.com, blishu@buaa.edu.cn, cilabus807@126.com Keywords: Ngrain, CAE, virtual maintenance training Abstract.
Secondly, according to the actual processes of the maintenance, we determine the key statuses of the digital prototype and build up the key frames.
But its’ visual effect is poor because of digital models do not have material, textures, and other details without CG processing.
After adding details such as material and materials, the models are imported into Ngrain software.
Actual verification shows that materials and textures of original models can be retained better in this method.

Especially focused on the overall function, the damage assessment of military engineering possessed the wide non-linear mechanisms, showing the typical complex characteristics about material, energy and information [1], which must reason the system damage from the overall functional vulnerability [2].
According to the structural characteristics of military engineering, and the component-based design idea of software engineering, damage assessment mechanism of component-based military engineering was established, as shown in Fig.1.
Through the searching process about the physical logic of the component units, physical damage parameters was reasoned, and then reasoning the system functions’ damage value of military engineering, which adapted to the special mechanism about the complexity of system structure, the diversity of system function and the non-linear perspective of damage key. 4.Rough Entropy Model on Damage Assessments Mathematical Problems of Damage Assessment for Component-based Military Engineering.
