Experimental and Finite Elemental Analysis of Bogie Suspension Mounting Brackets 2013-01-2789

In mining tippers, rear suspension plays a major role in defining vehicles ride and handling characteristics, stability and load carrying capacity. Bogie type of suspension is well suited for these applications. Bogie suspension mainly consists of bogie bracket, leaf springs and radius rods. Nonlinear static analysis is performed for a bogie bracket assembly considering bolt pretension and contacts to evaluate the static strength of bogie bracket. Since bogie bracket is connected to frame with several bolts, a sensitivity analysis is carried out to study the effect of bolt loosing on bogie bracket. The surface contact interaction (stick-slip) behavior between frame and bogie suspension mounting bracket is also studied. Good correlation is achieved with testing results.
