摘要： The distribution regularities of stress and displacement in the interior and on the surface of polyurethane coating are analyzed by the software of finite element analysis with the condition that the polyurethane coating of wind blade is impacted by the sand particle with different velocities and angles. The analysis results indicate that at the same impacting angle, the coating produces plastic yield more easily when the velocity of sand particle is faster and the range of the yield area is connected with the contacting time; plastic deformation wear and cutting wear on the surface of polyurethane coating are concurrent but have different effects; the sand particle impacting the coating can produce large tensile stress on the surface of the coating which causes the coating cracks to occur easily; the shear stress is symmetrically distributed on both side of the contacting point, and the coating at the contacting points lower left and lower right can be easily damaged by the shear.
