Abstract

An excavator is heavy equipment with a hydraulic system as the main drive and along with its uses, many parties have developed it as a means of production and as a means of learning. The education world needs excavators as learning tools and practice media are currently constrained by price when commercial units are used. Therefore, a learning media that is more compact but does not abandon the main essence of learning is needed. This research aims to analyze the front attachment design of the Zhugimada mini excavator using the finite element method. The research was carried out using the ANSYS application for the static load simulation process and testing was carried out with a bucket containing sand weighing 25 kg and using three hydraulic cylinders. The simulation results show that the maximum von Mises stress value in the bucket component is 43.226 MPa and the maximum deformation is 0,51285 mm in the tooth bucket so in general the design of the Zhugimada mini excavator front attachment components can be declared safe and can be continued in the fabrication process.

Abstract

The availability of practical facilities in mechanical engineering vocational education requires representative yet economical learning media. The development of a mini excavator demonstration tool by the Mechanical Engineering Department of Sekolah Vokasi Universitas Gadjah Mada (SV-UGM) is an effective alternative to support practical and research activities because it reflects the function and mechanism of an excavator with efficient costs and dimensions. This study analyzes the central body undercarriage design of the Zhuigimada mini excavator demonstration tool using the finite element method with the aid of Computer Aided Engineering tools. The material used is American Society for Testing and Materials (ASTM) A572 with a load of 19,620 N. The simulation results show a maximum von Mises stress of 21.69 MPa, a total displacement of 0.0133 mm, and a safety factor of 15.9. These values ​​indicate that the undercarriage design has good strength and stiffness against static loads produces an undercarriage design that is safe, efficient, and representative of the excavator work system.
