【摘要】：为了在限定的包络结构内完成小型激光器冷却部件的设计,并保证激光器和冷却部件的安装精度、发射天线的精度和水箱的散热能力,根据该激光器的技术指标,确定了采用的金属材料和焊接方式,进行了一体化和小型化设计。采用有限元分析软件和Solid Works软件对冷却部件中的重要零件进行静态分析,以确保其精度和可靠性。最后将加工完成的实物进行温度特性试验、冲击振动特性试验和高低温环境下叠加冲击振动试验。结果表明,冷却部件未出现撕裂、漏液等质量问题;激光器的束散角为2.5mrad,输出能量为86m J,脉宽为12ns,满足设计要求。该设计稳定可靠,可运用于多种机载激光测距机或指示器。
[Abstract]:In order to complete the design of the cooling parts of a small laser in a limited envelope structure, and to ensure the installation accuracy of the laser and the cooling parts, the accuracy of the transmitting antenna and the heat dissipation ability of the water tank, according to the technical specifications of the laser, The metal materials and welding methods are determined and integrated and miniaturized design is carried out. The finite element analysis software and solid works software are used to analyze the important parts of cooling parts in order to ensure their accuracy and reliability. At last, temperature characteristic test, shock vibration test and superposition shock vibration test are carried out. The results show that there are no mass problems such as tearing and leakage of the cooling parts, the beam divergence angle is 2.5mrad, the output energy is 86mJ, and the pulse width is 12ns, which meets the design requirements. The design is stable and reliable and can be used in many airborne laser rangefinders or indicators.
