Three-Dimensional Finite Element Analysis And The Strucrure Optimization Design Of Tower Equiment Non-Standard Shaft Lifting Lugs And Support Structure

With the development of large and heavy engineering equipments, thousands of engineering equipments are not rare now, and then ensuring them to be hoisted safely becomes more and more important. The usual method to hoist the engineering equipment is to combine the work of two heavy cranes, which needs designers to design the lug with main tail lifting point and the partial strengthen structures.Due to the length and weight of the tower equipment, combining the axial lug and tail lug to hoist the tower equipment is the common way. While the standard axial lug which bears no more than200t could not complete the hoisting of the heavy tower equipment, then non-standard design should be used during designing the lug of heavy tower equipment. Referring to the foundation structures of standard axial lug, the non-standard axial lug is preliminary formed in the way to design some strengthen structures based on detailed hoisting characters and choose the proper size of the lug structuresThe Finite element analysis of the designed non-standard axial Lug and its strength structures of partial mail tail lifting point and the tower equipment through ANSYS software could get the stress and deformation of all the structures then check the strength of them. Finally basing on the check result to figure out whether the non-standard axial lug and strength structures could hoist the related tower equipment safely.The paper mainly focuses on designing the lug and partial strength structures for some heavy tower equipments. It also focuses on checking whether the lug and partial strength structures could complete the safe hoisting of the heavy tower equipment as well as the strength of the designed non-standard axial lug, partial strengthen structures and the tower equipment. Conclude the rules that thickness of axial lug axial wall, lug axial diameter and the space of lug well stiffened plate influence on axial lug strength through optimizing analysis of axial lug, at the same time, achieve the optimizing analysis of the partial strengthen structure.
