高能光源下航空有机玻璃的性能与温升的计算

THE PROPERTIES OF AIRCRAFT ORGANIC GLASSES AND THEIR TEMPERATURE RISE UNDER HIGH-ENERGY LIGHT SOURCE

经测定YB-2、YB-4等航空有机玻璃对不同波长单色光有相近的透射能力。本文提出了关于航空有机玻璃对高能光源反射、吸收和透射能力的计算方法,并在此基础上解决了由复合光引起材料(或结构)温升的计算问题。航空有机玻璃在高能光线作用下沿深度产生表面高而内部低的温度梯度,使其机械性能发生相应的变化并产生一定程度的热应力。

The ditermination has shown that YB-2, YB-4 and other aircraft organic glas s es have similar transmission ability in relation to monochromatic light with different wave length. This paper establishes a method for calculating reflection, absorption and transmisson abillty of aircraft organic glasses relating to high-energy light source and thus resolves the problem of calculating temperature rise of material(or structure)caused by composite light. Under high energy light exposure, aircraft organic glass has a temperture gradient from surface to iner which results in corresponding change in mechanical properties and certain heat stress of certain degree.
