Intro to FEA and CAE
What multiphysics-based product development for BEV and FCEV means?
Multiphysics: the simulation or analysis of products by considering multiple physical phenomena interacting with each other e.g thermal structural fluid vibration electromagnetic etc
product development : engineering process of designing testing and validating components and systems
BEV runs solely on batteries and electric motors
FCEV uses hydrogen fuel cells to generate electricity to power electric motors.
FEA: a numerical method to solve complex real life problems by creating engineeing models with smaller and manageable elements.
Finite Element Analysis
Application of FEA:
- Structural analysis
- Thermal Analysis
- Fluid analysis
- Transient analysis
CAE stands for Computer-Aided Engineering.
CAE=FEA+Computer processing and simulation.
Integration of computational tools to support engineering design and analysis.
To evaluate how goods will function in real world scenarios.
Importance of FEA and CAE in engineering
- Reduce physical prototype development time and cost
- Accurate prediction of real-word performance
- failure rate prediction and performance optimisation
- reduced time to market.
AUTOMOTIVE INDUSTRY
