Stress and Fatigue Analysis of the Spray Boom of a Hanging Type Field Sprayer
Abstract
This study discusses deformation problems in field sprayer arms encountered in the literature. It compares the static stress and fatigue analysis of the sprayer arm designed with St 37 and St 44 materials. The sprayer arm is fully open for St 37 and St 44 structural steels with the weight force in the vertical direction y-axis generated by its weight effect in the analyses. According to the analysis results, the highest principal stress values and total displacement values are the same for St 37 and St 44 materials; the highest principal stress value is 87,147 MPa, and the highest total displacement value is 7,1729 mm. The safety coefficient for static stress analysis was the highest value for St 44 material and was 3,1556. The highest fatigue life belonged to the St 44 material; the result was 2,287×10^6 cycles. The highest minimum safety factor also belongs to St 44 material, and its value is 2,9273.
