Mechanical Characteristics of Composite Transmission Shafts for Commercial Vehicles
Through theoretical calculations,the load on the composite transmission shaft was deter-mined,and a finite element model of the transmission shaft was established in Abaqus.Based on the fi-nite element method,static analysis,modal analysis,and buckling analysis of the composite transmis-sion shaft,the composite and metal hybrid transmission shaft,and the metal transmission shaft were per-formed respectively,and the calculation results were verified.On this basis,Isight models for the com-posite transmission shaft and the hybrid transmission shaft were established,and the orthogonal design method was employed for scheme optimization.The optimized scheme enhanced the torsional strength,torsional stiffness,and first-order bending natural frequency of the two kinds of transmission shafts,as well as the buckling torque of the composite transmission shaft.Abaqus cohesive elements were used to simulate the adhesive layer,and the adhesive joints of the composite material were designed by analyz-ing the adhesive parameters.
