Analysis of Structural Integrity for the Hydro-reactive Metal Fuel Motor Grainl

摘要

摘要: 为研究鱼雷水反应金属燃料发动机高夹杂比燃料药柱在局部限位条件下的结构完整性问题, 开展了燃料药柱试样力学性能试验, 获得了药柱力学性能参数。在有限元软件中建立了燃料药柱试样的数值分析模型, 进行了药柱试样的力学性能仿真, 通过仿真结果和试验结果的对比, 验证了所建立的药柱力学本构模型的合理性。利用该力学本构模型对水反应金属燃料发动机中燃料药柱的结构完整性进行了仿真分析, 得到了燃料药柱的力-位移曲线、应力分布云图以及位移云图, 仿真结果表明, 燃料药柱在典型工况下未发生破坏, 径向和轴向的变形程度符合发动机整体结构要求。

Abstract: To study the structural integrity of a high-inclusion ratio grainl for a torpedo hydro-reactive metal fuel motor under local limit conditions, the mechanical properties of the grainl sample are tested, and the mechanical parameters are obtained. The numerical analysis model for the grainl sample is established using finite element software, and the simulation results are compared with the test results, which verified the rationality of the established constitutive model of grainl. The structural integrity of the hydro-reactive metal fuel motor grainl is analyzed using the constitutive model, and the force displacement curve, stress distribution, and displacement contour of the grainl are obtained. The simulation results indicate that the grainl is not damaged under typical working conditions, and the radial and axial deformation of the grainl can meet the requirements of the structure for a hydro-reactive motor.
