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。The test results of mode shape slopes can provide the necessary control parameters for the attitude control of missile, and can effectively check whether the installation position of missile sensing elements such as rate gyroscope is appropriate. The local deformation of the cabin section of the missile structure has a great influence on the modal slope parameters of the structure. Therefore,it is necessary for the missile to conduct the whole missile modal test to obtain the modal slope parameters. In this paper, taking the missile as the research object, from the aspects of mode shape slope measurement principle, mode shape slope measurement system design, etc., the research on the mode shape slope test system for measuring angular velocity at a designated point through a rate gyro and measuring reference point acceleration with an accelerometer is completed, which provides technical reference for subsequent similar tests.
