Analysis of Stress on Boom Excavator V EC650BE Using Finite Element Method

Abstract

In the current era of development, infrastructure is the driving wheel of economic growth. Company manufacturer of construction, headquartered in Góteborg, Sweden, named V Construction Equipment, is a large manufacturer of construction equipment in more than 140 countries. Excavators are heavy equipment and are usually used for excavation. This paper discusses the analysis of stress on the excavator's boom to determine the factor of safety. The boom of the excavator is V EC650BE. This study presents a step-by-step process of stress analysis calculation at the boom of the excavator. The method includes the determination of the type of material S690 QL Steel Plate. Analysis was then presented in linear statics using the finite element method to see the maximum stress that occurred on the excavator's boom. It is obtained that the value of the vonMises stress of 261.46 MPa. They have proven maximum breakout force at the position of 30°. The safety factor value analyzes the Boom stress at each configuration position numbered 3.07, 2.64, 2.94, 3.10 and 3.12. While the safety factor value analyzes the Boom stress at each variation of meshing size numbered 2.64, 2.61, 2.66, 2.67 and 2.67.
