The strength analysis of an agriculture truck chassis using finite element method

Abstract

The objective of this research was to analyze structural strength of agriculture truck based on basic global load case using finite element (FE) analysis software. The chassis of an agriculture truck made from Anan Karn Chang Agriculture Truck in Chatturat district, Chaiyaphum province, Thailand, was chosen for the study. The three-dimensional beam element type was applied in the study. The analysis was simplified based on static load and linear elastic material behavior assumption. There are four types of basic load behavior consisted of bending, torsion, longitudinal, and lateral loads considered. The results of maximum stress and deformations including construction stiffness were used as main parameters to evaluate the structural strength among load case. Regarding the results, it was found that the maximum stress occurred in torsion load was 164.57 MPa. The stress of bending load, longitudinal load and lateral load was 131.49 MPa, 147.08 MPa and 152.78 MPa, respectively. Furthermore, the bending and torsion stiffness of chassis were 7,399 N/mm and 6,415 N-m/degree, respectively.
