Based on the analysis of the shield performance for different shield parameters and impact parameters, the influences of shield spacing, thickness of wall, impact velocities and impact angles on the shield performance are discussed. The shield performance of the Whipple shield is not influenced by shield spacing, when the impact velocities are less than 3 km/s, but significant influence of shield spacing is evident when the impact velocities are at the range of v>3 km/s. Better shield performance is found in thicker shield. The ballistic limit curves have three different trends. The critical projectile diameter increases with impact velocities at the range of v≤3 km/s or v≥7 km/s, and decreases with impact velocities at the range of 3 km/s<v<7 km/s. Namely, the shield performance sees three different trends with the impact velocities ranging from 0 to 15 km/s. And better performance is expected with larger impact angle. A design method for Corrugated Stuffed Whipple shield (CSW) is given. The results of analysis show that shield performance for CSW improves with increase of corrugated angle. The shield parameters of CSW are established to protect spacecraft from small orbital debris impact., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=论述了流星体/空间碎片（M/OD）防护的重要性，给出了自主开发的空间碎片防护结构效能评价仿真平台总体框架。通过分析不同防护参数及碰撞参数条件下的防护结构效能，总结了防护间距、防护屏厚度、碰撞速度和碰撞角等参数对空间碎片防护结构效能的影响规律。针对基本的Whipple防护结构，碰撞速度v<3 km/s时，防护结构的防护效能不受防护间距变化的影响，碰撞速度v>3 km/s时，防护间距越大，防护结构的防护效能越好；Whipple防护结构的防护屏厚度越大，防护结构抗空间碎片撞击的能力越强，即其防护效能越好；在整个碰撞速度范围内（0~15 km/s），防护结构的防护效能呈现出3种不同的变化趋势，且防护结构的防护效能随碰撞角增大而提高。提出了一种波纹填充式防护结构，确定了可有效防护小尺寸空间碎片的防护设计参数。, authors=刘有英¹,王海福²,黄海¹,
