68环境技术/EnvironmentalTechnology技术专栏echnicalColumnT摘要：振型斜率测试结果可以为弹的姿态控制提供必要的控制参数，同时可以有效校核弹敏感元件如速率陀螺的安装位置是否合适。弹结构的舱段局部变形对结构的振型斜率参数有较大影响，因此，弹进行全弹模态试验以获取振型斜率参数十分必要。本文以弹为研究对象，从振型斜率测量原理、振型斜率测量系统设计等方面，完成了通过速率陀螺测量指定点角速度和加速度计测量参考点加速度的振型斜率试验系统的研究，为后续类似试验提供技术参考。关键词：模态试验；振型斜率；速率陀螺；加速度计中图分类号：V416文献标识码：A文章编号：1004-7204(2023)02-0068-05全弹结构振型斜率测试系统技术研究ResearchontheTechnologyofVibrationModeSlopeMeasurementSystemfortheMissileStructures路梓照1,2，崔英伟1,2，高世阳3，孙立明1,2，贾业宁1,2（1.天津航天瑞莱科技有限公司，天津300301；2.北京强度环境研究所，北京100076；3.海装北京局驻天津地区第三军事代表室，天津300301）LUZi-zhao1,2,CUIYing-wei1,2,GAOShi-yang3,SUNLi-ming1,2,JIAYe-ning1,2(1.TianjinaerospaceReliabilityTechnologyCo.,Ltd,Tianjin300301;2.BeijingInstituteofStructureandEnvironmentEngineeringBeijing100076;3.NavyEquipmentDepartmentofBeijingAgency,No.3MilitaryRepresentativeOfficeinTianjin,Tianjin300301)Abstract：Thetestresultsofmodeshapeslopescanprovidethenecessarycontrolparametersfortheattitudecontrolofmissile,andcaneffectivelycheckwhethertheinstallationpositionofmissilesensingelementssuchasrategyroscopeisappropriate.Thelocaldeformationofthecabinsectionofthemissilestructurehasagreatinfluenceonthemodalslopeparametersofthestructure.Therefore,itisnecessaryforthemissiletoconductthewholemissilemodaltesttoobtainthemodalslopeparameters.Inthispaper,takingthemissileastheresearchobject,fromtheaspectsofmodeshapeslopemeasurementprinciple,modeshapeslopemeasurementsystemdesign,etc.,theresearchonthemodeshapeslopetestsystemformeasuringangularvelocityatadesignatedpointthrougharategyroandmeasuringreferencepointaccelerationwithanaccelerometeriscompleted,whichprovidestechnicalreferenceforsubsequentsimilartests.Keywords：modaltest;modeshapeslope;r...
