Much of the fatigue damage in the tools and equipments of a auto shop can be limited to the compressive forces acting on them. Buckling under axial load is one of the most common failures which appear before crushing. This project is about “Buckling Analysis on a two post Screw auto lift”. The compression members, whom we come across, do not fail entirely by crushing. These members, which are considerably long when compared with their lateral dimensions start bending, i.e. buckling. When the axial load reaches a certain critical value, and screw auto lift is one such member. Both experimental and analytical work has been performed on a screw auto lift; employing commercial ansys program, based on the finite element method on a 3d solid model developed in pro/e.
The possible use of alloy steels(nickel steels) in place of mild steel has got improved properties like increase in the strength and the elastic limit of the alloy .The results suggest that use of the nickel steels improves the properties such as strength, ductility, and corrosion resistance over the specifications of the two post screw auto lift. .It also increases the durability of the equipment, two post screw auto lift.
