based on a 7-axis automatic fiber placement robot developed by our selves, we built up the geometric modeling, fiber placement pattern and a simulation software with following functions : mandrel shape design, fiber placement pattern production, and machine movement simulation . the paper first introduced automatic fiber placement and outlined the importance for research on the satellite triangle conjunction of frame . the detail for the geometric modeling process was described 本文以构架式卫星结构的接头零件为研究对象,并以高性能的自动铺丝技术硬件专用设备??七轴自动铺丝机器人为工作单元,结合复合材料结构设计的特点,开展了接头零件的几何建模、线型设计和仿真等研究工作,完成了simjoint仿真软件。
with the introduction of new pattern productions of electronic technology, such as new and low power integrated circuits, programmable application specific integrated circuits, microprocessor, etc, the function of nuclear spectrometry data acquisition system is stronger than before 随着电子技术新成果的不断引入,如采用新型低功耗集成电路、asic集成电路、微处理器技术等,核能谱数据采集系统的功能日益强大,性能也日趋完善,而计算机技术的迅速发展,为核能谱数据采集系统实现智能化、微机化等提供了必要条件。
