The student team "Jiu Tan" from our research group won the Excellence Award in the first SAM Domestic Structural Analysis Software Application Competition.

Team Information:

  • Team Name: Jiu Tan (玖探队)
  • Members: Lu Yuzhou, Liu Mingjing, Chen Jianying
  • Advisor: Lai Zhengshou
  • Institution: School of Civil Engineering, Sun Yat-sen University

Research Content: Their work "Comparative Study of Static and Modal Analysis of Offshore Wind Turbine Structures Using SAM and Abaqus" established a finite element model of an offshore wind turbine including tower, nacelle, hub, and simplified blades. Static and modal analyses were conducted using both SAM and Abaqus for comparison.

Results showed high consistency between the two software across 9 typical working conditions. In static analysis, the relative error of tower top displacement ranged from 2.1% to 3.5%, and the relative error of maximum equivalent stress ranged from 1.8% to 3.2%. In modal analysis, the relative error of natural frequencies for all modes was less than 1.5%. These findings validate the engineering applicability of the domestic CAE software SAM for wind turbine structural analysis.
