Abstract

Finite element software is used to check the strength of the rocket sled during recovery. In this paper, the finite element method is used to model the double track sled and the water brake. The water brake is loaded and the constraints, contacts and connections are defined. The water resistance of the water brake is loaded when the double track sled is recovered by using the fluid mechanics simulation. At last, the static analysis is used to analyze the force on the key parts of the double-track sled, and the strength of the whole sled is checked. At the moment of entering the water, the stress concentration occurs at the connection part of the sled exit with the body beam and the connection part of the support seat with the body beam, so the connection strength should be strengthened. This method provides technical support for body design, water brake design and sled recovery application.
