Stress and Model Analysis of Upper and Lower Bolster Components of Molten Steel Transfer Vehicle 2019-28-0119

The transportation of hot metal from blast furnaces to melting shops is carried out by molten steel transfer vehicle such as Torpedo ladle car in the steel plants. In need to design Torpedo ladle car within size limitation, capacity requirement and withstanding the impact, static, thermal shock and abrasion conditions, structural analysis is essential for validation. In this paper, stress and model analysis for upper and lower bolsters of Torpedo Ladle Car is carried out. The components are modelled in CAD and analysed using finite element method using software with the required boundary conditions. The results of structural analysis of bolster components are presented and discussed. The results shows that the deflection at the centre of upper and lower bolster was due to bending and applied load. The modal analysis predicted the natural frequencies by using block lanczos method.
