- X &
- Revolving-Frame Design: Design and develop high-strength upper and lower frames specifically optimized for battery mounting and protection in a 22MT class machine.

2.

Weight

Distribution &
- Stability: Re-engineer the machine’s center of gravity (CoG) to account for the removal of the engine/fuel tank and the addition of heavy Lithium-ion battery enclosures.
- Advanced FEA &
- Simulation: Perform complex Finite Element Analysis (FEA), Fatigue analysis, and Stress testing using tools like Ansys or Nastran to ensure a 10,000+ hour structural life.
- Boom &
- Arm Optimization: Design high-tensile work tools (Boom, Arm, Bucket) that can handle the instantaneous high torque delivered by PMSM motors.

5.

Material Selection: Select advanced high-strength steels to balance durability with weight reduction to improve energy efficiency.

- Vibration &
- Thermal Integration: Design structural mounts that dampen high-frequency vibrations from electric motors and integrate cooling paths for the thermal management system.
