Analisis Kekuatan Rangka Mini Excavator Electric Menggunakan Aplikasi Solidworks

The development of heavy equipment technology is leading to the use of electric drive systems as an effort to reduce exhaust gases and increase energy efficiency. One of the components that plays an important role in electric mini excavators is the frame, because it functions as a support for all components and receives loads during the operation process. Therefore, a frame strength analysis is needed to ensure the structure is able to work safely according to the loads received. This study aims to analyze the strength of the electric mini excavator frame using the Finite Element Analysis (FEA) method with the help of Solidworks Simulation software. The material used in the frame is ST 37 steel with a static load of 2,000 kg distributed in the component mounting area. The parameters analyzed include Von Mises Stress, Displacement, and Factor of Safety (FOS). The simulation results show that the maximum stress value that occurs is still below the material yield stress limit, while the maximum displacement value is still within acceptable limits. The Factor of Safety value obtained must be in the range of 2.5 - 3, thus indicating that the frame design is in a safe condition for the given load. Based on these results, it can be concluded that the electric mini excavator frame design has adequate structural strength and is suitable for use as a basis for further design development.
