Introduction of 4-Axle Lowbed Semi Trailer
It benefits by enhancing transportation effectiveness and guaranteeing road safety. The low-bed semi-trailer’s main bearing element, the frame, directly affects how well the vehicle performs. The strength and stiffness of a low-plate semi-trailer are investigating in this paper using finite element analysis.
Longitudinal Beam of 4-Axle Lowbed Semi Trailer
The longitudinal beam uses an I-shaped section made of 16Mn material and has a stepped construction to accommodate the demands of low-bed semi-trailers. For 4-axle low-bed semi-trailer manufacturers in China, the gooseneck is design to have a flexible cross-section and the height of the suspension support is as low as possible to guarantee that there is adequate room for the hoisting mechanism and the suspension system.
Arrangement of Stringer Reinforcement Plates
The inner and outer reinforcement plates are weld with the I-beam to form a box-shape structure. There are several plug welding holes on the lower reinforcement plate, which are connect to the lower wing surface of the I-beam through plug welding and break welding on both sides.
Reinforcement Plate of Lowbed Semi Trailer Manufacturer in China
The ends of the inner and outer reinforcing plates are fashion into a U shape to lessen stress concentration. For 4 axle manufacturers in China, the end of the lower reinforcement plate adopts a 45° inclined plane, and the ends of the inner and outer reinforcement plates are avoid.
Cross Beam structure
The cross beam, which serves as the frame’s principal structural element and joins the left and right longitudinal beams, is employe. The longitudinal beam’s internal stress and its distribution are directly impacts by the torsional performance of the beam itself. A reasonable beam design may guarantee that the frame made in China has enough torsional stiffness.
Suspension Support for 4-Axle Lowbed Semi Trailer Manufacturer in China
The bottom side of the longitudinal beam is directly weld to the front, middle, and rear suspension supports. At the front, middle, and back supports are three box-shape beams with bigger cross sections. On this basis, it is assume that the frame has enough torsional stiffness and can more effectively transmit the load.
The Connection Between The Beam and The Longitudinal Beam
The joint stiffness of the connection between the beam and the longitudinal beam directly affects the overall stiffness of the frame, and the rational design of the node structure of the beam and the longitudinal beam is a serious problem in the design of the frame. There are usually two forms of connection between beams and longitudinal beams.
Bottom Structure of The Frame
The frame uses a wooden bottom plate in the load-bearing area and a patterned panel for the remaining portion of the frame in order to provide the bottom plate of the frame some flexibility and prevent the track from slipping. To guarantee safe transportation, anti-skid ribs are position suitably. The hardwood base plate is fasten to the beam of the semi-trailer made in China using countersunk head screws.
