Design, Analysis and Optimization of Overhead Crane Girder

Abstract

In the current material handling equipment the life of the overhead crane as well as the
cost of the material handling equipment is too important to stay in the competitive market of the
industries. The cost of the material handling equipment is depend on the weight of the material. The
performance of the material handling equipment will be done by the working on the optimization of
the overhead crane used in the industries. In this project, Design, Analysis and Optimization of the
overhead bridge crane girder for the 75 ton capacity is carried out by changing the dimensions of
section of overhead crane girder. In Design we are using 750 x 450I section for girder and calculate
stress (98.251 ????/????????2
) ,deformation(9.8844 mm), safe factor(0.87734),and weight(26976 Kg).In
the Analysis of girder analyze of von misses stress (98.251 ????/????????2
) ,deformation(9.8844 mm), safe
factor(0.87734).
From analysis and analytically we found weight of girder is higher so that optimization is required
for the optimize weight of girder.In the optimization, we have selected different sizes (740 x 440,
730 x 430, 720 x 420, 710 x 410, 700 x 400) of I section of girder. We have found out deformation,
stress and weight of girder for different section. Fromthat, Optimum section (700 x 400) is found out.
For Optimum section, Value for von misses stress is 117.61 /????????2
. Value for Deformation is
12.228 mm and Value for Weight is 24455.
