液体火箭发动机推力室极限承载能力研究

Analysis of loading limit of the LRE thrust chamber

基于MSC Patran/Marc软件的循环对称分析功能和材料、几何双重非线性分析功能,对液体火箭发动机推力室进行了计算分析,得到其极限承载能力,并给出了结构的极限承载能力曲线。

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.
