【正文】 indicate that, Using ANSYS / LSDYNA established simulation model of blast shocking vibration of electronic equipment, which can better reflect the response characteristics of electronic equipment under the condition of the actual explosion. Further basicly verify the feasibility of the use of the model.4 Analysis of importance of factors The damage of blast vibration of electronic equipment has many environmental impact factors, the main aspects of battlefieldrelated, including: Vibration source characteristics, the media, an explosion height, the distance between objectives and local oscillator, they have different damage effect on the equipment. This paper will be based on the above model, using the orthogonal experiment to analyze the degree of influence of various factors. According to the equipment’s working environment, this paper selects the amount of explosives A, medium density D, the distance S between the equipment and Burst points, the highth H of the Starting explosion that four factors have (peak acceleration) effect on Point B which is in the cavity body on the ground. Selecting the appropriate level of data may get the Table 3 of factor. 表3 各要素因子水平取值FactorA1S2D 3H4138025313682 Table 3 The values of cytokine levels of elementsIn view of the four design factors of this experiment, each factor takes three levels in order to get more test information and to ensure the rational use of the factor level values, so it selects the orthogonal table. Well, according to nine sets of data patterns to test [5], making the extreme difference analysis and getting the extreme data Table 4 of the vibration acceleration of the orthogonal Bpoint .Table 4 the result data of the orthogonal test試驗號A1S2D3H4B點加速度值(E06)①1111②1222③1333④2123⑤2231⑥2312⑦3132⑧3213⑨3321ⅠjT=ⅡjⅢjRj From the experimental data we can see that the impact of various factors on the indicators of the degree is different. One blast from the Swave transmission of vibration greater impact, explosion height H is less, by paring the value of Rj can be very poor impact of each factor was the specific in order: S A D H. 5 Conclusion Electronic equipment, shock and vibration studies injuries is a plex system engineering. At present, the study of the issue using numerical simulation methods, mainly due to blast vibration damage in live realdetonation test of objective conditions, demanding, and there is shock and vibration platform can not be used on the plex structure of the group of pieces of testing measurement problems. In this paper, ANSYS / LSDYNA simulation procedures, the shock and vibration damage of electronic equipment, simulation of the basic ideas and methods are basically consistent with the conclusions of practical engineering, and environmental impacts of major factors of the orthogonal test and analysis, for indepth shock and vibration damage to electronic equipment, simulation study provides some reference.參考文獻：[1] [J]．中國機械工程．2002，13:11631170.[2] 田娟. 電子裝備沖擊振動損傷仿真研究[D].軍械工程學(xué)院碩士學(xué)位論文．2008，2:56.[3] [D].軍械工程學(xué)院碩士學(xué)位論文．2007，3:3032.[4] 時黨勇，李裕春，[M].北京:清華大學(xué)出版社，2005，4:126140.[5] 《正交試驗設(shè)計法》，03：117121.作者簡介:石 全（1966），男（漢），河北遷安人，教授，博士生導(dǎo)師，主要研究方向為裝備戰(zhàn)場搶修。田慶偉（1978），男（漢），黑龍江木蘭人，碩士研究生，主要研究方向為電子裝備爆炸沖擊振動損傷。王廣彥（1976），男（漢），河北邢臺人，講師，博士研究生，主要研究方向為裝備維修工程。The introduction of the Authors: Shi Quan (1966 ), male (Chinese), Hebei Qian39。an people, professor, doctoral tutor, the main fields of research for equipment battlefield.Tianqing Wei (1978 ), male (Chinese), Heilongjiang Mulan people, postgraduate, the main fields of research for blast vibration damage of the electronic equipment .WANG Guangyan (1976 ), male (Chinese), Hebei Xingtai people, lecturers, doctoral students, the main fields of research for equipment maintenance. 聯(lián)系方式：第一作者：田慶偉通信地址：軍械工程學(xué)院裝備管理與指揮系裝備管理教研室郵 編：050003聯(lián)系電話：13832308058Email: sunlixian1983@
