摘要
本文提出一种0°和90°缠绕角圆和非圆截面梁在拉弯载荷作用下的变形计算方法。本法将圆或非圆截面梁化分为有限个梁元进行位移、应变、应力分析,通过坐标转换,将各梁元的位移和载荷在梁上进行整合,从而得出0°和90°缠绕角圆或非圆截面梁在拉弯载荷作用下的分析模型。文中将理论计算结果与有限元数值计算结果进行对比,理论计算结果与数值实验结果有较好的一致性。结果说明,本文提出的计算方法可应用于0°和90°缠绕角圆和非圆截面梁在拉弯载荷作用下的分析计算。
The work here presents a calculation method for displacements of 0°and 90°winding angle circular and non-circular cross-section beam under tensile and bending loadings. The method involves dividing the beam into finite beam elements, analyzing the elements displacements, strains and stresses of beam elements, transforming the coordinates, integrating displacements and loads of beam elements on the beam and obtaining the displacements of beam under tensile and bending loadings. Comparison between theoretical results and numerical results are done and they have a good agreetment. The results show that the presented method can be used for calculating the displacments of 0°and 90°winding angle circular and non-circular cross-section beam under tensile and bending loadings.
