Abstract

The strap-on linkage equipment on the current launch vehicle is more difficult to satisfy the load design requirement of the new generation high-thrust strap-on launch vehicle. According to the research of the new linkage equipment technology, this paper studies the force transmission path optimization and designs one category of hyper-static force transmission path schemes. Through the analysis, an optimal scheme of the force transmission path is selected. A combinatorial optimization strategy of the force transmission path of high-thrust strap-on launch vehicle is designed based on the iSIGHT platform. Firstly, multi-island genetic algorithm is used to explore the region where the globally optimal solution lies and then the exact optimal solution is approached by sequential quadratic programming. The optimized force transmission path can substantially reduce the load of the strap-on linkage equipment and also satisfy the requirement of the attitude control system design.
