  • Hybrid lightweight rear axle for electric vehicles

    Oct 02, 2017 · The rear axle's load is decreased by this shift. The critical and design-driving load case is acceleration during a cornering manoeuver. In this case, bending as well as torsion loads act on the axle, leading to a multiaxial state of loading. A second relevant load case is the maximum of the vertical wheel-load resulting from running over a curb.

    Appropriate test cycle is required for engine testing. To do so, a new methodology is developed for deriving Engine Test Cycle based on real world duty cycle. Transient speed and load is to be collected from the functional engine on the field. The duty cycle for cyclic operation will be developed from the actual transient speed and load conditions.

  • Experimental Investigation of Wheel/Rail Rolling Contact

    Dec 11, 2012 · In this research, a test rig was developed to control rolling of a full size wagon wheel carrying a pre-determined level of vertical load effectively across the railhead edges of test specimens. The vertical, lateral and shear strains developed at the railhead end face close to the wheel contact zone was determined using the PIV method.
