AI Technical Summary
Existing technologies for straddle-type monorail vehicle body structures suffer from problems such as high weight, high production costs, large welding deformation, complex structure, and difficulty in modular production, making it difficult to achieve lightweighting, fewer parts, and greening.
The carbon steel coupler seat, traction rod seat, and driver's cab are joined to hollow aluminum alloy profiles through multi-point riveting to form a modular vehicle frame. By combining riveting and welding, uniform force transmission and weight reduction are achieved.
This achieves lightweight and high-strength vehicle body, reduces production difficulty, improves production efficiency, enhances the modularity and automation of the vehicle body structure, and meets the requirements of green production.
