Design and FEA of 125T Face Shovel Excavator’s Arm

Abstract:

In manufacturing industry investors are always looking for economical and safe designs to cope up with the increasing demands of competitive markets. Keeping this objective in mind, arm of CE125 face shovel hydraulic excavator was re-designed to decrease manufacturing cost by reducing weight while keeping the stress approximately same as was used in the conventional design. For this purpose Pro/EngineerTM was used to generate Computer Aided Drawing (CAD) where cross section and inner structure of the design were kept to be semi-elliptical which helped to decrease the weight of the arm significantly. Initial stress analysis was also done in the same CAD software as it is quick and optimization can be done quickly. However sometimes it does not give accurate results because of poor meshing, so final analysis was done in AnsysTM. Analysis in AnsysTM calculated the stress to be 114 MPa while displacement came out to be 3.8 mm. Comparison of two models showed that the weight of new design is 5.1% less than the conventional one.
