用于空间探测的静电分析器轻量化设计与验证 [PDF]

open access: yesKongjian kexue xuebao, 2023
针对空间探测载荷的轻量化需求,以空间等离子体探测的静电分析器为研究对象,进行了轻量化设计和验证。在材料及加工方式选择方面,充分利用增材制造这一新兴加工手段,打破传统轻量化设计时追求低密度材料的思路,对比多种材料及加工方式下设备重量及力学表现,确定铝合金为主要材料,3D打印为主要加工方式。在结构设计方面,基于3D打印加工的优势,在减小设备各部分结构厚度的同时,适当设置加强筋以解决薄壁在后处理时易产生形变的问题。采取上述方案设计的设备质量减少至1.2 kg,比使用镁合金及传统加工方式的设备质量(2.2 kg)
