Weight Optimization of Roller Shaft of Pad Steam Machine

Abstract

The roller shaft of a continuous pad steam machine suddenly appeared the abnormal when it was running condition in textile industry which effects on maintenance of machine, time, cost, productivity importance etc. This paper present the material analysis, weight optimization and stiffness characteristic of roller shaft of pad steam machine maintaining the integrity of the specifications. A 3D model is created in Catia V5RI to mating to design, optimization and finite element analysis of roller shaft used in pad steam machine which is made of carbon steel material. The FEA was done in HYPER WORK software (Nastran & Optistruct) in two parts preprocessing and post processing by using four different materials based on their composition viz. Carbon steel AISI 1040, EN8, EN24, and AISI 6150. The parameter like von misses stress, deformation; maximum and minimum principal stress & strain were obtained from analysis Software. Santosh D Dalvi et. al. also worked on this system in 2017 by comparison of existing and new material AISI 1040. FEA show that the EN24 Material is best suggested material among all also find out results like weight and stiffness parameter. It is resulted of 12.527 % of weight with reduction in deformation. Performed two mechanical test i.e. tensile test and hardness test as per ASTM on sample specimens; results show that the strength and hardness are within the limit. This research work is improving shaft parameters which are used in textile industry, heavy duty application etc.
