摘要：

针对光触发电子测压仪在多点测试过程中容易受火炮膛内复杂环境（高温、高压、强电磁）的影响等问题，通过设计合理的光窗结构，增强测压仪外壳的密封性能和整体强度；采取在光窗处附着一层电磁屏蔽薄膜的措施，降低来自火炮发射时产生的电磁干扰。在模拟复杂条件下，采用有限元分析软件对改进后的测压仪光窗及壳体进行强度仿真，同时对壳体的电磁屏蔽性能进行分析。仿真结果表明：改进后的光触发电子测压仪壳体满足膛压测试要求，电磁屏蔽性能得到进一步改善。通过实验测试，验证光触发结构设计的合理性和有效性，达到系统的设计要求。

Abstract: The study designs reasonable optical window structure, enhances manometer shell sealing performance and strength for solving problems such as light-triggered electronic manometer easily influenced by the complex environment(high temperature, high pressure and strong electromagnetic interference) of the artillery chamber pressure in the process of multipoint test. The external electromagnetic interference is reduced by attaching a layer of electromagnetic shield film to the optical window. In conditions of complicated simulation, finite element analysis software is used for high intensity simulation to improved optical window and shell of manometer and analysis on shell electromagnetic shielding performance. The simulation results show that the improved light-triggered electronic manometer meets chamber pressure testing requirements and the electromagnetic shielding performance has been further improved. The rationality and effectiveness of light triggered structural design meet the system design requirements.
