| Abstract: | Based on the functions of cyclic symmetry analysis, material and geometric nonlinearity analysis of the finite-element general program MSC Patran/Marc software, a thrust chamber of LRE （liquid rocket engine） is calculated and analyzed. As a result, the ultimate bearing capacity of the structure is given and the corresponding curve of the loading capacity is offered. |
