曲梁通常的设计方法,是假设梁在弯曲以后仍然是平的,梁的水平横断面仍然通过曲率中心。实际上,梁的水平横断面在弯曲后已不是水平的。不过在大多数情况下并不严格限制。但是,在认真分析梁在稍微弯曲时,就会发现上述问题。本文介绍的方程式虽然是近似的,但能提供较准确的结果。通常应力集中系数Ki,Ko是补偿系数,用于补偿由于假设曲梁是直的而做的简化。Ki是指最接近于曲率中心的边缘纤维的系数, The usual design method for curved beams is to assume that the beam is still flat after bending and the horizontal cross-section of the beam still passes through the center of curvature. In fact, the horizontal cross-section of the beam after bending is not horizontal. However, in most cases it is not strictly limited. However, in the careful analysis of the beam is slightly bent, you will find the above problems. Although the equations presented in this paper are approximate, they provide more accurate results. The usual stress concentration coefficients Ki, Ko are the compensation coefficients used to compensate for the simplification made by assuming that the curved beams are straight. Ki refers to the coefficient of the edge fiber closest to the center of curvature,
