Optimization of an Aluminum Platform for Electric Buses
Letenda, an innovative company specializing in electric buses, commissioned Lx Sim to simulate side impacts on their new aluminum structure. The goal was to validate the structural resistance according to public transit certification standards (TC, APTA), while accounting for unique design constraints and a modular layout that can accommodate various configurations based on client needs (number of seats, seating arrangement, etc.).
Challenges
- Working without reference data due to the innovative nature of the design
- Meeting strict regulatory impact test requirements
Solutions
FEA Simulation
- Virtual reproduction of test conditions required for certification
- Analysis of critical structural zones in the event of a side impact
- Identification of weaknesses and potential improvements without compromising modularity
Design Optimization
- Close collaboration with Letenda’s team to propose realistic structural adjustments
- Integration of manufacturing and configuration constraints into the recommendations
Results
Thanks to simulation, Letenda was able to:
- Improve the structural resistance while respecting design constraints
- Avoid significant costs associated with physical prototypes
- Invest early in the development phase in a certifiable and high-performance product
This project demonstrates the power of simulation to innovate with confidence, while reducing development risks and costs.
