	Structure optimization of strap-down inertial navigation system support (EI CONFERENCE) 会议论文 OAI收割 2011 2nd International Conference on Mechanic Automation and Control Engineering, MACE 2011, July 15, 2011 - July 17, 2011, Inner Mongolia, China 作者: Wang J.; Sun H.; Sun H. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 In order to meet the requirement of inertial navigation components and minimizing the system's weight and topological optimization was conducted. Then topological optimization and size optimization were conducted under conditions of random vibration and impact. Firstly according to the dynamic characteristics of missile and requirement of inertial navigation system the structure of inertial navigation support was designed according to types of missile connection and space arrangement of electronic components the method of transforming multi-loading cases to multi-loading constraints was used to optimizing the size of the support under conditions of random vibration and impact. Comparing to the original support structures RMS accelerations in installed points reduced by 25.2% under random vibration the weight of optimal structures reduced by 28.1% the structures also met the requirement of inertial navigation system under condition of impact. The support structure shows improvements in both dynamic characteristic and light weight comparing with the original one. 2011 IEEE.
