- 摘要:
- 针对液氧煤油发动机管路中广泛应用的软金属密封结构，采用单边接触模型和材料弹塑性模型相结合的方法，通过有限元软件Nastran隐式非线性模块对其进行数值仿真。得到并分析了结构应力、位移及接触应力等相关参数。结果表明，软金属密封结构在45 MPa内压下，结构强度满足使用要求，密封面接触应力大于300 MPa，密封安全系数大于1.67。
- Abstract:
- The soft metal sealing structure widely used in LOX/kerosene rocket engine was numerically simulated by means of the Nastran implicit nonlinear module and the method which combines the contact model and material elastic-plastic model. The relevant parameters such as structure stress, displacement, contact stress and so on are analyzed. The result shows that the intensity of the soft metal sealing structure can satisfy the requirement of application when it is at the pressure of 45 MPa, the contact stress of the sealing surface is above 300 MPa, and the sealing safety factor is more than 1.67.
