在梳理航天器机械总体设计现状的基础上,将设备三维模型进行分类和参数化,应用Pro/Program技术建立三维模型模板库,结合对Pro/E的深度集成,实现了由设备接口数据自动生成实例化三维模型,提高航天器设备建模效率和准确性。通常,航天器设备中有70%～80%是相似的,形状比较规则且一般为机箱类设备,如图1所示:只有20%～30%设备形状不规则,包括圆柱状、球状及外形极其复杂的设备。因此,可以通过
On the basis of combing the overall design status of the spacecraft machinery, the three-dimensional model of the equipment is classified and parameterized. The Pro / Program technology is used to build a three-dimensional model template library. Combined with the deep integration of Pro / E, the three- Instantiate 3D models to improve the efficiency and accuracy of spacecraft equipment modeling. Generally, 70% -80% of the spacecraft devices are similar, and the shapes are relatively regular and are generally chassis type devices, as shown in Figure 1: only 20% to 30% of the devices have irregular shapes, including cylindrical, spherical and profile Extremely complex equipment. Therefore, we can pass
