摘　　要：依据有机玻璃窗设计手册对锥面边界球冠有机玻璃观察窗进行初步设计。结合该类型有机玻璃观察窗的几何形式和受力情况给出其结构应力理论计算公式,并据此进行观察窗的优化设计。对设计的观察窗建造实尺度样机进行压力筒测试,监控实时应变和极限载荷,对结构应力和极限载荷理论计算值进行验证。The preliminary design of a conical edge spherical crown type acrylic observation window is fulfilled according to the acrylic window design handbook. The theoretical formula for its structure stress is proposed according to the geometric form and force conditions, and then the design optimization is carried out based on the formula. A full scale prototype of the observation window is built and tested in the pressure tank where its stress and ultimate load are monitored in real-time to validate the theoretical structure stress and ultimate load calculations.
