| 目的 弄清某型引信在高温高湿环境下的失效模式，研究高温高湿环境对引信薄弱部件的影响。方法 利用ANSYS workbench软件，类比热扩散仿真，建立湿扩散仿真方法。以某型引信为研究对象，开展湿仿真、热仿真、湿-热-机械耦合仿真，根据仿真计算结果，找出薄弱部件，分析其老化失效模式。结果 在环境温度为85 ℃和相对湿度为85%条件下，仿真时长设定为1 h，结果显示，引信内部温度传递基本达到饱和，湿度分布梯度明显，产生的应力集中和变形量最大在涡轮电机外壳，达0.19 mm，并产生了约17 MPa的应力集中，与真实样品出现的失效部位与失效模式高度一致。结论 高温高湿环境下，湿-热耦合应力将导致引信出现缺陷，缺陷集中在电机外壳处。 |

| The work aims to study the effects of high temperature and high humidity on weak parts of fuze, so as to find out the failure mode of a certain type of fuze in high temperature and high humidity environment. ANSYS workbench software was used to simulate thermal dispersion and establish a wet diffusion simulation method. With a certain type of fuze as the research object, wet simulation, thermal simulation and moist-thermal-mechanical coupling simulation were carried out, and according to the simulation calculation results, the weak parts were found out and their aging failure behavior was analyzed. Under the conditions of ambient temperature of 85 ℃ and relative humidity of 85%, after 1 hour of simulation, the internal temperature transmission of the fuze basically reached saturated state, the humidity distribution gradient was obvious, and the maximum deformation of the product due to humid thermal stress was 0.19 mm in the turbine motor housing, and a stress concentration of about 17 MPa was generated, which was highly consistent with the failure site and failure mode of the real sample. Therefore, in high temperature and high humidity environment, the hygrothermal stress will cause defects to the fuze, and the defects will be concentrated in the motor housing. |
