Weight Optimization of Single Girder of EOT Crane By Using Different Types of Cores of Sandwich Structure

mechanical engineering

Sandwich panels with high modulus/high strength skin material and low density/low modulus core material have higher stiffness-to-weight ratio than monolithic panels. This construction has often used in light weight applications such as aircrafts, marine applications, and wind turbine blades. Almost all industrial equipment falls in the category of heavy weight material of I beam section. Hence it is essential to study and optimize the weight and strength in various composite structures. The structural analysis of sandwich panels with C40 face sheets and core is done using ANSYS work bench. Bending stress and deflection is compared with I beam section in analytically. The models of the I Section web core, X(cross) core, and Vf core sandwich structures are done in CATIA V5R20 and weight is analyzed. The aim of thiswork is reduce the weight, deformation and increase the strength. Deformation compared the experimentally by using Universal Testing Machine with analytically as well as summarized the proposed technique for reduction in weight, which will help to investigate the various aspects of weight reduction and strength improvement of various cores i.e. Web core, X core, and Vf core.
