Buckling Analysis of Cyclone Separator Using Solidworks

Buckling Analysis of Cyclone Separator With Different Position of Stiffner Using SolidWorks

Aim:- To perform buckling analysis of cyclone separator and find buckling of stand at different position of Stiffner.

Theory:-

In engineering, buckling is the sudden change in shape of a structural component under load such as the bowing of a column under compression or the wrinkling of a plate under shear. If a structure is subjected to a gradually increasing load, when the load reaches a critical level, a member may suddenly change shape and the structure and component is said to have buckled.

Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capacity. However, if the deformations that occur after buckling do not cause the complete collapse of that member, the member will continue to support the load that caused it to buckle. If the buckled member is part of a larger assemblage of components such as a building, any load applied to the buckled part of the structure beyond that which caused the member to buckle will be redistributed within the structure. Some aircraft are designed for thin skin panels to continue carrying load even in the buckled state.

Factor of Safety

For the ductile material used here the material factor of safety (FOS) is defined as the material yield stress divided by the von Mises’ effective stress.In engineering, a factor of safety (FoS), also known as (and used interchangeably with) safety factor (SF), expresses how much stronger a system is than it needs to be for an intended load. Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.

Objective:- To calculate factor of safety for different position of stiffner in cyclone separator stand by performing buckling analysis.

Here Buckling Factor maximise at 1000mm

Design Study 2:-

Offset Range:- 200mm to 1800mm

Steps:- 200mm

Buckling Factor of Safety:- 25

Results

Here Buckling Factor maximise at 1000mm

Design Study 3:-

Offset Range:- 600mm to 1050mm

Steps:- 50 mm

Buckling Factor of Safety:- 25

Here buckling factor of safety maximise at 900mm,950mm,1000mm,1050mm.

Conclusions:-

For the above study it can be concluded that buckling factor of safety is maximum at 900mm and above

i.e as the stiffner is offseted at different dimensions the buckling factor of safety changes and dimension with more that 25 factory of safety is obtained
