Abstract
This work presents a failure analysis of the the frame of the grass cutting system of a Flail Mower model FLV 225 (Herder). Studies of impact and erosive wear are performed with the objective of minimize the damage to this protective component. The speed of the particles is evaluated at collision and ejection. The erosive wear analysis aims to quantify the volume of material lost due to the impact of the projectile against the frame. To minimize damage, surface treatments and protective coatings are investigated. The methodology is based on numerical modeling via the Abaqus commercial package. Two representative geometries for the impact particles are adopted. Different shapes, weights and impact angles are analyzed. It was demonstrated that the sharp particles are the most harmful to the frame. Six solutions are proposed and evaluated using a decision matrix.
