简介
Highlights
- 3D scanning allows analysing the wear morphology on used ploughshares.
- The method shows a polynomial trend of the abrasive wear.
- The cutting edge profile does not markedly change along the ploughshare.
- Ploughshares located behind the wheels underwent the higher wear for soil compaction.
- The method is a potential basis for wear prediction and design optimization.
During tillage, soil engaging tools are exposed to very critical working conditions due to soil friction. This produces an abrasive wear which needs to be monitored in order to avoid high costs for machine maintenance and fuel consumption and a deterioration of tillage quality. A commonly used method for wear diagnosis is the evaluation of the mass loss and volume change after a prolonged component usage. The instruments generally used for the assessment of these two quantities give only general and punctual information about …
