| 摘 要： | 根据NEPE推进剂的组成及结构特点,采用ANSYS10.0有限元计算软件,建立了NEPE推进剂轴对称有限元计算模型.对NEPE推进剂在单轴拉伸作用下损伤破坏趋势进行了模拟.通过对应力集中因子α和脱粘角θ的比较,讨论了固含量、键合剂加入量、氧化剂组成及氧化剂粒度等推进剂的组成与结构条件的变化对其在单轴拉伸作用下损伤破坏趋势的影响.结果表明,采用所建立的NEPE推进剂轴对称有限元计算模型所模拟的力学性能规律与实验研究的趋势符合得很好.

| Abstract: | According to the composition and structure properties of the NEPE propellants,the finite element calculation model of the NEPE solid propellants was established by the ANSYS 10.0 finite element calculation software. The damage trend and variation regularity of the NEPE propellants under unilateral tensile was simulated. Effects of the solid particle content,bonding agent content,composition and particle diameter of the oxidant on the damage trend of NEPE propellants were discussed by comparing the stress co... |
