理论推导出光纤横向效应所带来误差的误差修正公式。
Theoretically the error correction formula caused by the crosswise effect of the optical fiber is deduced.
通过三维光弹实验测定了轴表面横向半椭圆裂纹的应力强度因子(SIF),并计算了与光弹轴裂纹几何及当地应力相对应的无限大体的SIF,从而求得SIF修正系数。
The SIF and its correction factor of the transverse surface semi-elliptic crack of a photoelastic axle are tested and studied with the method of three dimensional photo-elastics.
为此,本文在设计中把横向振动的影响考虑进去,提出了可行的修正方法。
There fore I the influence of cross-vibration is considered in design, and a practical correction method is given in this paper.
