Rover Structural and Thermal Analysis for Lunar and Earth Environments

This report details the structural and thermal considerations for a rover designed for lunar exploration and launch from Earth. Key findings include the rover's total mass of approximately 29.1 kg and dimensions of 0.407 m x 0.497 m x 0.456 m. Stress analysis on the motor shaft indicates a maximum allowable mass of 61.4 kg under lunar conditions. Additionally, shaft diameter requirements are presented for various operational phases including launch, soft landing, and lunar operations. The report also discusses buckling stresses and energy usage under different thermal conditions.
