In order to forecast and optimize the longitudinal stiffness of the V-type thrust rod applied to heavy-duty commercial vehicles, the hyperelastic constitutive model of rubber material in the V-type thrust rod is built based on uniaxial tension and compression experiment for rubber specimens. Then the dynamic finite element simulation for the work process of the V-type thrust rods are carried out using Abaqus software. The longitudinal stiffness of the V-type thrust rods is predicted using the post processor module of Abaqus software. The relationship between the V-type thrust rod's longitudinal stiffness and the structure of the spherical hinge is studied according to the strain contours of the rubber layer. The simulation results demonstrates that increasing the width of the plastic layer in the spherical hinge can improve the V-type thrust rod's longitudinal stiffness, because this structure can change the volume and vulcanization area of the rubber layer and block rubber layer extend to end covers. Bench tests for the samples of the primary structure and optimized structure are carried out, and the results show that the prediction and optimization method is valid. This method can shorten the R&D period of the V-type thrust rod and dramatically improve its longitudinal stiffness. ©, 2015, Nanjing University of Aeronautics an Astronautics. All right reserved.

To improve the strength of spherical hinge in V-type thrust rod applied to heavy-duty commercial vehicle, a 3D model and a finite element model of V-type thrust rod are established. A whole vehicle virtual prototype based on a heavy-duty commercial vehicle is established by using the software ADAMS. The limit load of V-type thrust rod is obtained from many-body dynamic emulation. The dynamic finite element simulation for the working process of V-type thrust rod subjected to limit load is carried out by using the software Abaqus. The stress nephograms of rubber in spherical hinge are obtained by using the post processor module of Abaqus. The stress nephograms of rubber demonstrate that, for the purpose to improve the strength of V-type thrust rod, it is necessary to increase the diameters of steel coat, end cap and gasket properly, or to groove the plastic layer, while removing plastic layer will decrease the strength of the spherical hinge. The simulation result may facilitate the spherical hinge optimization of V-type thrust rod. Source

The thrust rod is the key load-bearing part of the balanced suspension on heavy commercial vehicle. In order to optimize the structure and study the durability of it, we carried out the force and simulation analysis. In this paper, the model of thrust rod and guide mechanism was simplified. Under all driving conditions, force analysis was done for fully-loaded vehicle and force calculation formulae of thrust rods in different directions were derived. Multi-body dynamics model of the vehicle was established with ADAMS and we compared the differences of the two algorithms. Then the results of the two algorithms were compared with the load spectrum test results. We find the calculated results are in good agreement with engineering requirements. © (2013) Trans Tech Publications, Switzerland. Source
