High-speed wear tests on mower blade from various manufactures using the wear pot method

Autor: Maksim Barbashov, Markus Gellings, Semih Özen, Andreas Jahr

Publikováno v: agricultural engineering.eu, Vol 79, Iss 2 (2024)

Rotary mowers are often used for forage harvesting in agriculture, as this technology can achieve a high throughput. These knives are therefore exposed to high levels of wear and tear, and will also be often changed because of loss of material by bad

Synthesis and Analysis of a Novel Linkage Mechanism with the Helical Motion of the End-Effector

Autor: Alexey Fomin, Daniil Petelin, Andreas Jahr

Publikováno v: Robotics, Vol 9, Iss 3, p 53 (2020)

The proposed study is focused on the development of a novel modification of the slider-crank mechanism, the kinematic scheme of which is organized by coupling planar and spatial (screw) kinematic chains. The structure of this mechanism provides the e

Determination of the properties of cereal stalks when being bent and cut with the aid of a universal test bench

Autor: Andrej Batos, Maximilian Ruepp, Andreas Jahr, Burkhard Corves

Publikováno v: Landtechnik, Vol 70, Iss 4 (2015)

Für die Messung der Biege- und Schnitteigenschaften halmartiger Güter wurde ein Universalprüfstand entworfen. Die mit ihm ermittelten Messwerte dienen der Erstellung von Simulationsmodellen zur Abbildung landtechnischer Schnittprozesse. In der vor

A Novel Test Method to Determine the Wear Resistance of Agricultural Cutting Tools with an Analyzing Method Based on an Ellipse-Fit Algorithm

Autor: Andreas Jahr, Robert Bongartz, Hunn Sim, Alex Pillmann

Publikováno v: Conference Papers in Science. 2015:1-6

Cutting belongs to the essential techniques in many fields of application in agricultural engineering. Cutting tools in agriculture are exposed to a high amount of abrasive wear and impact stress. Increasing the wear resistance of cuttings tools has
