Structural Analysis and Optimisation of Industrial Crane Arm
Keywords:
Stresses, Displacement, Optimization, Weight reductionAbstract
A crane is a type of machine, generally equipped with a hoist, wire ropes or chainsthat can be used both to lift and lower materials and to move them horizontally. Aim is to reduce the weight of the crane by reducing the thickness at few areas where ever applicable and also maintaining the weight carrying capacity.Structural analysis is the determination of the effects of loads on physical structures and their components. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, vehicles, machinery, furniture, attire, soil strata, prostheses and biological tissue. Structural analysis incorporates the fields of applied mechanics, materials science and applied mathematics to compute a structure's deformations, internal forces, stresses, support reactions, accelerations, and stability. The results of the analysis are used to verify a structure's fitness for use, often saving physical tests. “Structural analysis ” will be carried out to find the following.
- Mechanical response of the structure, subjected to applied loads and boundary conditions.
- Analysis results will include deformed shape of the structure, displacements and the stresses in various locations.
- Following Pre checks are done before Boundary Conditions and loads are applied to the model i. Elimination of Free Edges and T-connections in the model. ii. Minimizing Triangular elements. iii. Assignment of material and physical properties to the respective components created
- Optimize to reduce weight and stress concentration on the ARM and displacements due to weight.
- The final design is achieved by removing the unwanted material and by reducing the thicknesses that were ever applicable from the Basic design
