本文利用轮胎受荷前后表面反射光波的干涉原理,从布喇格方程出发,导出了干涉条纹间距与变形量的关系式,分析了内部缺陷与条纹畸变的关系.
In this paper, based on the interference principle of the surface reflected light waves before and after the tire is loaded, the relationship between the interference fringe spacing and the deformation is derived from the Bragg equation, and the relationship between the internal defects and the fringe distortion is analyzed.
