A Review on FEA and Optimization of Backhoe Attachment in Hydraulic Excavator

Excavators are used primarily to excavate below the natural surface of the ground on which the machine rests and load it into trucks or tractor.Due to severe working conditions, excavator parts are subjected to high loads.The excavator mechanism must work reliably under unpredictable working conditions.Thus it is very much necessary for the designers to provide not only a equipment of maximum reliability but also of minimum weight and cost, keeping design safe under all loading conditions.It can be concluded that, force analysis and strength analysis is an important step in the design of excavator parts.Finite Element Analysis (FEA) is the most powerful technique in strength calculations of the structures working under known load and boundary conditions.In general, computer aided drawing model of the parts to be analyzed must be prepared prior to the FEA.It is also possible to reduce the weight of the mechanism by performing optimization task in FEA.This paper provides the platform to understand the Modeling, FEA and optimization of backhoe excavator attachment, which was already carried out by other researchers for their related applications and it can be helpful for development of new excavator attachment.
