摘　　要：源带通滤波器是一种用于军备环境下的电子信号滤波器件。由于其工作环境的特殊性,有必要针对其使用环境的需求和适应性,对滤波器结构可靠性和热性能进行有限元仿真,包括结构随机振动、冲击,以及内部器件热生成和滤波器结构的热能传输状态。结果表明,该滤波器在随机振动下的变形量和结构应力都在使用环境要求范围内,并满足坠撞安全冲击指标要求,结构安全可靠;其次,器件在热平衡后稳态温度均小于内部电子设备额定工作温度,滤波器能稳定工作。另外,在器件实现电源信号处理功能的前提下,通过有限元仿真,校核了其工作可靠性,为微波器件振动和热设计提供了仿真思路。The source band pass filter is a kind of electronic signal filter used in military environment.Due to the particularity of its working environment,it is necessary to conduct finite element simulation on the reliability and thermal performance of the filter structure according to the needs and adaptability of its use environment,including random vibration and shock of the structure,as well as the heat generation of internal devices and the heat transfer state of the filter structure.The results show that the filter's deformation and structural stress under random vibration are within the range of application environment requirements,and meet the safety impact index requirements,and the structure is safe and reliable.Secondly,the steady-state temperature of the device after thermal balance is less than the rated operating temperature of the internal electronic equipment,and the filter can work stably.In addition,under the premise of realizing the power signal processing function,the reliability of the device is checked through finite element simulation,which provides a simulation idea for the vibration and thermal design of microwave devices.
