To get vibration characteristics of the support  FEM model of the support was created with Ansys  and then response characteristics were analyzed on the support under the separated random loads during carrier flight  including the phases of subsonic and subsonic. To validate the analysis method  wide band random vibration test was done on the points of the support  which are used for mounting inertial instruments. The comparison of the analysis and the test data shows that the relative error of analysis result is not more than 13%. According to the two results the support structure was improved. Finally random vibration analysis was carried out on the improved one. The result shows that the acceleration response was largely reduced than before. This research can be a reference of performance improvement of the strapdown inertial support and navigation system precision. 2011 IEEE.   量子点/染料复合敏化与修饰 会议论文 中国化学会第二十五届学术年会论文摘要集（下册）, Abstracts of the 25th CCS Congress(Ⅱ), 中国化学会第二十五届学术年会, 25th CCS Congress, 中国吉林长春, CNKI, 中国化学会 吴学明; 王鹏; 罗芬; 马蓓蓓; 王立铎; 邱勇; Xueming Wu; Peng Wang; Fen Luo; Beibei Ma; Liduo Wang; Yong Qiu 收藏  |  浏览/下载：4/0 High-speed photodetector characterization using tunable laser by optical heterodyne technique - art. no. 60200A 会议论文 conference on optoelectronic materials and devices for optical communications, shanghai, peoples r china, nov 07-10, 2005 San, HS; Wen, JM; Xie, L; Zhu, NH; Feng, BX 收藏  |  浏览/下载：78/16  |  提交时间：2010/03/29 optical heterodyne technique  ultra-wideband frequency response  different frequency photodetector  FREQUENCY-RESPONSE MEASUREMENT  MULTIMODE WAVE-GUIDE
