摘要
为摸清微光像增强器塑料外壳受力规律,掌握质量变化特点,运用形变理论,建立硅橡胶形变数学模型,拟合塑料外壳受力曲线,据此确定微光像增强器塑料外壳出现开裂的必然性和寿命周期特点。结果表明:数学模型与试验数据高度吻合,能够表征塑料外壳受力情况及寿命变化规律。
To determine the law of stress on the plastic shells of image intensifiers and to identify the characteristics of quality change,the deformation theory is used in this study to establish a mathematical model of silicone rubber deformation and to fit the stress curves of plastic shells.Accordingly,the inevitability and life-cycle characteristics of the plastic shells of image intensifiers are determined.The results show that the mathematical model is in good agreement with the experimental data and can characterize the stress conditions and life variations of plastic shells.
