摘要：

Currently, the dotted strap-on linkage of launch vehicle has caused excessive concentrated load in the working process. In order to solve the problem, it's presented for the first time that a linear separation system can be applied to the issue of bundled separation between the central stage and the booster. And then linear bundled separation device is optimized to improve the power transmission efficiency and realize the lightweight design. FEM analysis is used to discuss the separation and linkage principle of linear bundled separation device, by simulating stress during binding and the separation process under transient internal pressures. Based on multidisciplinary optimization platform Isight and ABAQUS, the optimization design of linear bundled separation device is completed. Compared with the traditional dotted strap-on linkage, the optimized linear bundled separation device can lose the weight of the launch vehicle 48%, and the problem of excessive concentrated load is effectively solved. Design of linear bundled separation device and the analysis-optimization system will provide reference for our country's typical structures of launch vehicle in the future. © 2019 Journal of Mechanical Engineering.
