“…The structure belongs to the lap joint, but it has the characteristics of a T-joint under load. This structure often appears in the weld of steel assembled wheels [1], as shown in Figs. 1 (b) and (c), and it bears the complex dynamic radial load, circumferential load, and lateral load in operation [2].…”

The SW400 fine-grained high-strength steel T-lap joints were welded by submerged arc welding. The influence of welding technology on the geometrical characteristics of welds and fatigue performance of the joints were studied by radial fatigue test with different welding parameters. The numerical analysis was used to study the characteristics of the stress distribution. And the fatigue fracture morphology was analyzed by scanning electron microscope. The results show that with the increase of welding line energy, the thickness of the weld increased, and the propagation direction of the fatigue crack changed from the weld to the base metal. When the thickness was less than 4 mm, the high-stress region was in the area of the weld around the weld root, and the fatigue crack propagated to the weld. When the thickness was greater than 4.5 mm, the high-stress region of AE and AS were in the weld around the root, where the crack propagated to the weld, while in the middle of the weld high-stress region was in the area of base metal around the weld root, crack propagated to the base metal. With the increase in the thickness of the weld, the maximum mises stress decreased, and the crack propagation rate decreased. The time of crack initiation was very short, which occurred in the high-stress region of the weld root in the middle of the weld.

This paper presented a numerical analysis of the damping characteristics of truck escape ramps. To explore the procedure of out-of-control trucks running into arrester beds, the discrete element method (DEM) models of both the tire and the truck escape ramp were built. Tire compression tests were conducted on a homemade tire test system, and the results were used to calibrate the parameters of the tire DEM model. A compression machine was used to conduct dynamic compression tests on pebbles obtained from escape ramps, and the results were used to calibrate the parameters of the pebble DEM model. Road tests were then conducted to further validate the simulation method. An adaptive master-slave simulation procedure analysis was utilized in the simulation process. The error of the travel distance between the simulation and test results was 2.95%. The built tire-pebble DEM model was used to perform the simulations of trucks running into truck escape ramps with different truckloads and laying depths. The results of different truckloads indicated that the truck speed was mainly determined by the laying depth at the entrance of the truck escape ramp. With an increase in time, the truckload started to take effect. The results of different laying depths indicated that the truck speed results were approximately constant at the entrance of the truck escape ramp. As the laying depth increased, the truck speed decreased. When the laying depth exceeded approximately 60 cm, the damping properties of the different laying depths were approximately constant.

Wheels are important safety components in the vehicle driving system. Automobile lightweight is the direction of the modern automobile development. In this article, steel wheel lightweight was studied. The equal strength design of rim was used to reduce the weight of the wheel. Stress analysis of the wheel was studied using UG/Nastran. A professional software WheelStrength was used to predict the radial and cornering fatigue lives of the wheel. Sheet stamping process was set up to analyze the interference fit between the disk and the rim. The assembly was simulated by axisymmetric finite element method. After calculation and analysis, the stress distributions and fatigue lives for rim under different load cases have been found. The thicknesses of wheel rim bead and the interface between rim and disk cannot be reduced. Stress and fatigue simulation results were compared using different thicknesses of the optimized region. It was found that the best thickness of the optimized region was 1.5 mm. Spinning was used to form the flared preform. The thickness of the rim after spinning and rolling forming agreed well with the simulation. The results of fatigue tests indicated that the lightweight wheel met the design requirement. The weight of the rim was reduced by about 14%.
