摘要
以带有悬臂结构的同轴脉冲形成线为研究对象,开展提高振动环境适应性的优化设计。首先,通过实际工况分析及仿真计算,确定形成线内筒的盲孔螺钉可采用的防松措施有:使用施必劳螺纹并涂抹防松胶;优化螺钉数量。其次,通过仿真分析和绝缘试验,优化尾端绝缘子材料,提高悬臂支撑的中内筒连接刚度。最后,开展振动试验考核,优化后的形成线等效件可以通过长时间的振动考核,相比优化前的振动环境适应性有很大提高,验证了优化设计的有效性。该研究结果对同类型脉冲功率源的振动环境适应性设计具有参考意义。
Taking the coaxial pulse forming line(PFL)with cantilever structure as the research object,wecarried out an optimization design for improving the vibration environmental adaptability.Firstly,through the analysisof the actual working condition and simulation calculation,the available anti-loosening measures for the blind holescrew in the inner conductor were determined as follows:using spiralock thread,applying anti-loosening glue andoptimizing the number of the screws.Secondly,the insulator material was preferred to improve the connectionstiffness of the inner conductor and the middle conductor according to the simulation analysis and the insulation testresults.Finally,the vibration test was carried out to verify the effectiveness of the optimization design.The result showthat the optimized equivalent parts of PFL could pass the long-term assessment,indicating that the vibrationenvironment adaptability was greatly improved.The research results have reference significance for the vibrationenvironment adaptability design of the same type of pulse power source.
