The invention discloses a bionic crossbar-free semi-trailer frame which comprises a spine tubular beam, a plurality of variable-section transverse beams, edge beams and variable-section through transverse beams. One end of each variable-section transverse beam is connected with the spine tubular beam in a meshed manner, the multiple variable-section transverse beams are arranged on two sides of the spine tubular beam, the other ends of the multiple variable-section transverse beams positioned on the two sides of the spine tubular beam are connected with one another by the edge beams, the variable-section through transverse beams are positioned at two ends of the spine tubular beam, and the spine tubular beam and the edge beams are integrally connected with one another by the variable-section through transverse beams. The bionic crossbar-free semi-trailer frame has the advantages that abilities of various components can be sufficiently played, accordingly, full-bearing effects can be realized, the dead weight of the bionic crossbar-free semi-trailer frame can be reduced, raw material consumption can be decreased, fuel consumption of a vehicle can be reduced when the bionic crossbar-free semi-trailer frame is used, the unbalance loading probability of the frame can be decreased, stress conditions of tires can be improved during running, abrasion of the tires can be relieved, the service lives of the tires can be prolonged, the frame is structurally stable and is high in running stability, and carried goods can be effectively protected by the vehicle.
