摘　　要：介绍了火箭弹性模型实验技术，包括模型对火箭的质量分布、刚度分布的模拟，模型的加工制做，激振机构的研制，支撑元件的研制以及几期实验的结果综合。In this paper,the buffet experimental technique of aeroelastic model for launch vehicle is presented,including the aerodynamic shape of model,mass and stiffness distribution.Several test results are introduced in brief.We find that there are negative damping values in some tests.Based upon our research for ten years about this subject,the aeroelastic model experimental technique for launch vehicle has been developed successfully.
