The dump body of the off-highway dump truck is the large, prime structure, used to carry overburden and coal in mines. The body structure is subject to severe vibration, impact load, and oscillation events due to rough terrain conditions in the mines and the loading of rocks from a certain height from the shovel. Presently, the body mounting design is chassis pivot pin mounted, rubber rail seated, and has guide plates to lock transverse movements. Despite all these mounting arrangements, the body structure oscillates (or rattles) due to multiple field factors. The most effective solution to the problem is to provide an additional oscillation-arresting structure so that body stability is achieved and undesirable body-frame impact is avoided. The prime objectives of this study are to design an additional oscillation-arresting structure and to select an appropriate material to work at an ambient temperature of -50°C (sub-zero temperature); to carry out the structural behaviour of the existing material (works in normal temperature). The structural design is validated through classical hand calculations and Finite Element Analysis (FEA), qualifying it by Von Misses stress, shear stress, and displacement criteria. Recommending the most suitable material for sub-zero temperature (-50°C) application.
