HOT FORGING DIE DESIGN OPTIMIZATION USING FEM ANALYSIS FOR NEAR-NET FORMING OF 18CRNIMO7-6 STEEL PINION SHAFT

The objective of the presented work was to develop a new forging process for a pinion shaft as a component of a wind turbine.A study of near-net-shape forming using Deform 3D software was performed to reduce operational cost, time, and material scrap; enhance specific properties; increase productivity.Near-net forged products have good dimensional

Leveraging nationally representative survey data on 443,680 respondents from January to March 2021, this study examines the temporal, spatial, and sociodemographic variations in COVID-19 vaccine hesitancy in the U.S.Findings reveal multidimensional determinants of vaccination intentions involving confidence, complacency, and circumspection factors.
