Collar clamps & winch frame assembly
Collar Clamps
Designed adjustable collar clamps to interface the payload winch frame with the UAV’s structural boom. The clamps were engineered to slide along the boom axis, enabling micro-adjustments during final physical integration and allowing the team to easily optimize the aircraft's center of gravity (CG) and component clearances.
CAD Assembly & Integration:
Handled the geometric design using SolidWorks, extracting interface dimensions from the existing assembly to properly configure and align critical hardware mounting holes.
Design Validation & Optimization:
Modeled a simplified structural test fixture of the aircraft frame to verify physical clamp fitment and sliding clearances.
Conducted Finite Element Analysis (FEA) to map stress concentrations under maximum operational loading conditions.
Iterated on clamp geometry, sizing, and structural fillets based on FEA data to reinforce high-stress zones while shedding unnecessary mass.
Manufacturing Preparation:
Performed a comprehensive tolerancing analysis on all critical holes and mating faces to ensure reliable sliding fitment and secure clamping force.
Design Trade-off Analysis:
Evaluated standard hose clamps as a lightweight, low-complexity alternative, but ultimately proceeded with the custom machined/printed collar design to ensure superior structural rigidity and precise alignment under flight loads.
