Abstract

Deep soil loosening machine MAS 65 is destined to work soil at depths exceeding 45 cm, thus the machine’s frame is subjected to loads which could affect its structural integrity. Within this paper a static structural analysis was performed on the machine’s 3D model using finite element method and strain and stress distribution maps were created. Using the Von Mises stress map there were identified several critical points which could fail during normal exploitation conditions and which should be monitored by strain gages during field tests in order to prevent structural failure.

Highlights

Agricultural machinery are self-propelled working machines or driven from alternative power sources, designed for performing a series of works within agricultural processes, according to agricultural-biological and technical-economical requirements imposed.Generally, conception of an agricultural machine starts from its physical operations which have to be executed during operation
The resistance structure, frame or chassis, is designed and dimensioned according to a strength reserve which assures the good development of the activity, choosing for it an adequate material [3]
This primary structure is subjected to a first process of structural analysis for an improved or even optimal design [4, 5, 6]

Summary

Introduction

Agricultural machinery are self-propelled working machines or driven from alternative power sources, designed for performing a series of works within agricultural processes, according to agricultural-biological and technical-economical requirements imposed. The resistance structure, frame or chassis, is designed and dimensioned according to a strength reserve which assures the good development of the activity, choosing for it an adequate material [3] (so to be able to withstand maximum strain which does not affect the work quality and maximum loads in the structure which cannot cause damage). This primary structure is subjected to a first process of structural analysis for an improved or even optimal design [4, 5, 6]. In the design stage is very important to dimension the structure for operating in complete elasticity conditions
