| Abstract: | Through the combination of mechanics and finite element,the suspended pipeline is simplified as a large deflection beam.ANSYS is used to establish the large deformation finite element model.Strain distribution and variation are studied under the condition of different spans.Based on the pipeline strain design criterion the safety assessment is promoted.The results show that the maximum tensile strain appears on the pipeline surface around the side,the largest compressive strain appears on the pipeline surface of middle span.The strain increases rapidly after the span of 25~30 m.When the span is 50 m,the strain reaches to 0.006 15,and the pipe will be damaged easily. |
