AI Technical Summary
The existing semi-trailer longitudinal beams are prone to local twisting and deformation under complex road conditions or heavy cargo loading, and cannot effectively resist torsion.
X-shaped reinforcement frames and thickened wing panels are introduced into the longitudinal beam structure. The torque is dispersed and transmitted at multiple angles through the reinforcement frames, and thickening and weight-reducing holes are added to the wing panels to enhance the structural strength and load-bearing capacity.
It effectively reduces the local torsional deformation of the longitudinal beam, enhances the structure's anti-torsion ability, reduces weight and expands the bearing area, and avoids damage caused by excessive local pressure.
