Wind Mill Towers. . .

Wind Mill Towers are one of the most interesting projects with which FEA Engineering is dealing.  The towers were designed to be an easy to service structure, and to have a pleasing aesthetic impact on the surrounding environment while satisfying all the design criteria for a such complicated structure. In order to achieve these goals FEA Engineering once again employed Algor’s FEA tools, using the Mechanical Event Simulation capabilities (Accupack module).

In order to simulate the tower’s response under different types of loading, advanced nonlinear FE analyses was utilized.

Two different design options were analyzed:

  • Round, tapered shaft
  • Multisided, tapered shaft

The response of the structures were analyzed under wind loadings, high axial load combined with high wind load and ground motion (earthquake situations).

The response of the structures were analyzed under wind loadings, high axial load combined with high wind load and ground motion (earthquake situations). The models were conceived and built to capture with high accuracy the stress distribution in all critical areas.

The output file provide important information such as:

  • Anchor bolts reactions & stresses
  • Shaft – Base plate welded connection stress distribution
  • Flanged connection stress distribution
  • Dynamic induced loads

    • The models can simulate any imaginative work condition for these structures: wind from any direction, ice load, earthquake, traffic or vortex shedding dynamic induced loads, impact loads or combinations of these. Are also simulated the dynamic induced loads by hub-blades  assembly, in motion.

    This simulation environment offers the most efficient engineering tools to design and optimize any type of free standing structure subject to high axial loads or dynamic induced loads.
