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.   Computer Simulation Of Random Sphere Packing In An Arbitrarily Shaped Container 期刊论文  OAI收割 Cmc-Computers Materials & Continua, 2008, 页码: 109-118 作者:  Li SX;  Zhao L;  Liu YW(刘曰武) 收藏  |  浏览/下载：1007/78  |  提交时间：2009/08/03 Sphere Packing  Random Packing  Computer Simulation  Relaxation Algorithm  Containers  Numerical-Simulation  Hard-Spheres  Particles  Generation  Binary  Impact  Mesh
