Topology Optimization Design and Performance Comparison of a Land–Air UAV Rotary Arm Integrating Additive Manufacturing Constraints

This study achieves a 30.8% mass reduction in amphibious UAV rotary arms via additive manufacturing-constrained topology optimization (AM-constrained TO), establishing lightweight design as the primary objective. To evaluate structural efficiency, we systematically compare three strategies: AM-const...
