Investigation of hydraulic excavator using dfma

Abstract

Excavators are the most commonly used equipment for various purposes in construction activities. The operation of booms, arms and buckets for pushing, pulling, lifting and digging/lowering in excavators are carried by hydraulic cylinders. Based on the quality issues during assembly and in the field, as reported by the manufacturers, on hydraulic cylinders and front axle assembly of excavators, the present research work has been carried by analysing the components of hydraulic cylinders and front axle assembly using DFMA (Design for Manufacture and Assembly) in two separate case studies. newline
