Shape Optimization and Analysis of Arm of an Excavator

Abstract

Excavator is heavy gadget consisting of an articulated arm (backhoe), bucket and cab
installed on a pivot (a rotating platform, like a Lazy Susan) a pinnacle and undercarriage
with tracks or wheels. Their layout is a herbal development from the steam shovel.
Excavators are meant for excavating rocks and soils. Excavators may have a mechanical or
hydraulic force. Hydraulic excavators are the maximum crucial group of excavators. The
Arm of an Excavator performs an essential function in the ordinary performance ofan
excavator as it is connecting part between the bucket and body of an excavator. This study
focuses on the design of Excavator arm with mass optimization. CATIA is used for modelling
and ANSYS is used for the Analysis of the arm. Static analysis is carried out to know the
working stresses. Further model analysis carried to see the mode shapes under full load and
no load conditions. A comparative study is made between the existing and optimized designs.
