Today’s industry requires versatile, efficient, and cost-effective equipment while improving flexibility and productivity. This study designs an I-section cantilever beam for a 0.5 ton floor-mounted jib crane, selecting ISMB-200 instead of ISMB-250 to reduce cost while maintaining efficiency and flexibility. Structural behavior is evaluated using analytical methods, ANSYS finite element analysis, and experiments with strain gauge techniques, including modal analysis via FFT-based measurements. Results show analytical vs FEA stress/deformation errors of 18% and 8%, with natural frequency differences between 4% and 18%, and an optimum beam for lifting 500 kg.

Design optimization and Modal Analysis of Cantilever I-section Beam For 0.5 ton capacity of Floor Mounted Jib Crane 1Vishwanath S. Chavan, 2 Shrikant S. Waydande 1Research Scholar, 2Assistant Professor 1, 2 D. Y. Patil Institute of Engineering and Technology, Ambi, Pune, India Abstract: Today’s industry demands versatile, efficient, and cost effective equipment while at the same time providing more flexibility along with significant savings through increased productivity. Most of the researcher’s did work on static analysis of I-section for by using Analytical and Software basis. One of them ISMB-250 beam are taken for 0.5 ton capacity of Floor mounted jib crane. The purpose behind the design of I-section cantilever beam for 0.5 ton capacity of Floor mounted jib crane is that to reduce the cost, make more efficient and to provide more flexibility. Hence instead of ISMB-250 beam, ISMB-200 beam is selected for reducing cost, more efficient and more flexibility. To check behavior of ISMB200 beam for Floor mounted jib crane in the form of stresses & deformation using Analytical, ANSYS and Experimental (Strain gauge technique). The additional part in this project is Modal analysis. The purpose of modal analysis is to measure the dynamic vibration characteristics such as (Natural frequency, deflection) by using Analytical and Experimental (FFT Analyzer). The differences error between Analytical and FEA values of stress and deformation in the form of percentage are 18% and 8%. Similarly the stresses error difference between Analytical and Experimental are approximately near to 4%. The difference error between the natural frequencies is varying from 4% to 18%. From observing the below results, for lifting 500kg load the optimum I-section beam for Floor mounted jib crane is ISMB200. Due to this selected beam cost is reduced by 30% as compare to existing (ISMB250 beam). Future scope in this project is to perform harmonic response analysis using experimental and numerical. Keywords: Design, structural analysis, modal analysis, strain gauge technique. I. INTRODUCTION Now a day’s material handling system manifests anisotropic behaviour. Ajib crane can help to improve material handling efficiency and work flow. Serious consideration should be given to jib cranes for applications requiring repetitive lifting and transferring of loads within a fixed arc of rotation. Jib cranes are some type of lifting and hoisting machines used in the industry commonly. Their design and manufacturing processes are developing from day to day because of economic conditions and rivalry between companies. These factors enforce them to decrease the time used for the design and production of machines. For these machines, some classification studies were done in catalogues and books. Jib cranes are either attached to a building column or cantilever vertically from an independent floor mounted column. Floor mounted jib cranes is directly fixed on the floor without any support to keep it upright. To increase the lifting capacity and minimize the cost and time for building a ship and offshore structure, block lifting with multi-cranes becomes more and more important. There are different types of jib cranes, but we analysis of floor mounted jib crane In this study, designing of I- section cantilever beam of capacity 0.5 ton for floor mounted jib crane The jib crane requires at least two times Maintenance in a year. The current task has been taken to reduce the servicing required & to ensure smooth functioning without any breakdown. The important parameters are determined such as stresses, deflection, & lateral torsional buckling behaviour of regular I section cantilever beam of floor mounted jib crane subjected to uniformly distributed load(ownweight) & a concentrated of load at free end, is done by using static analysis. This project investigate stresses deflection & natural frequency using Analytical, finite element analyses & experimental and compare
