摘　　要：将螺旋体分解成螺旋轴和螺旋叶片两部分,建立LS200螺旋体结构的CAD模型,并对其进行有限元网格的划分。为验证该模型的正确性,对LS200螺旋体进行静力和稳定性的有限元分析,并将试验结果与计算结果相对比,验证了模型的正确性和精度。A CAD model of LS200 helical structure is established by dividing the helical body into helical axis and helical blade and finite element meshing is performed. In order to verify the correctness of the model, finite element analysis is carried out for static and stability of the helical body and the comparisons of test results with calculation results demonstrate the correctness and precision of the model.
