Mechanical Analysis and Design University of Galway - Full Curriculum Program 2022/2023 Year - Galway

This module introduces detailed design methodologies used for designing load-bearing mechanical engineering machine components based on analytical solutions, empirical techniques and test results. It also contains a hands-on lab based CADD element for design and anlayis of common mechanical components, elements, structures and mechanisms.

Learning Outcomes
1. Formulate design problems, assess, design and plan an iterative design process, factors of safety, codes and standards, economic analysis, reliability estimation, and design constraints can be used and their rationale, advantages and limitations understood.
2. Use free body diagrams to calculate resultants in superimposed loading situations, Mohr?s circle to obtain principle stresses and their orientations, apply failure theories for brittle and ductile materials including Maximum Shear Stress Theory and Distortion Energy Theory and use of stress concentration factors.
3. Definition and understanding of basic fracture mechanics and defining parameters, analysis and design components subjected to fatigue loading, S-N diagrams for medium, low and high cycle fatigue, endurance limit modifying factors, Goodman diagrams, factors of safety and cumulative fatigue damage theories in design.
4. Design power screws, bolts and fasteners, bolt preload analysis and bolted joints, helical compression and extension springs, roller bearings and bushings, lubrication, journal bearings, viscosity and hydrodynamic theory.
5. Perform force analysis of gear trains and do design analysis of stresses in spur gears. .
