Analysis On Structural Strength Designing Of Rocket Sled

This thesis bases on theory of the strength and security of rocket sled. It aims at finding out problems in intense designing of rocket sled and trying to seek the proper approach.Firstly, the thesis focuses on the analysis and brief calculation of the force of the moving monorail rocket sled. The results indicate that rocket sled can achieve the required speed under this circumstance. Secondly, the author sets statics mathematical model of rocket sled, and calculates its greatest counterforce by the application of the formula. What's more, the author sets structure model of rocket sled by using Microsoft SolidWorks, then under the assistance of Microsoft ANSYS, the author conducts numerical simulation and gets stress nephogram,deformation and safety factors, by which the reasonable structural designing is achieved. Finally, the thesis briefly makes the simulation analysis and clarifies the modes of vibration and frequency of rocket sled. The finding proves that monorail rocket sled would not fail to work because of resonances in a short time.To a certain extent, this thesis provides technical support for the structural designing of rocket sled; meanwhile, it can also be of practical value to other related structural designing of rocket sled.
