高强度带光窗光电外壳设计

Design of High Intensity Photoelectric Package with Optical Window

摘要:

选取窗口结构强度相对较弱的圆形平面玻璃光窗外壳,就该类外壳最薄弱的带光窗管帽受力状态进行了有限元分析,根据强冲击下结构与应力的变化趋势优化设计了管帽结构,结果显示经结构优化的管帽能承受1×104 g的强冲击,满足光电器件封装的高强度要求。

Abstract:

Taking the circular flat package with weak glass window as the research object,the under-force status of the cap with optical window was analyzed with the method of finite element.The cap structure would be modified according to the variation tendency of the cap's structure and stress under strong impact so as to satisfy the requirement of high strength packaging.
