Abstract: |
The strap-on equipments' load calculation is the key work for the hyper-static launch vehicle design, because it is the base for the configuration analysis, the structure design and optimization. In this paper, the analytical model of the hyper-static launch vehicle is deduced by the force method, and is verified by the finite element method. Based on the analytical model, the load affected by the stiffness of the strap-on equipments, the installation site and the number of the equipments is analyzed. The research result provides reference and theoretical support for engineering applications. |
