Yan, Y. (author), Pargalgauskas, S. (author), Helmons, R.L.J. (author), Schott, D.L. (author)A convex pattern surface is proposed and optimized to mitigate the sliding wear of bulk handling equipment caused by interaction with bulk solids. This work investigates the effectiveness of the convex pattern surface on wear reduction during interactions with non-spherical particles. Multiple representative particles, obtained through a...journal article 2024

Mohajeri, M. (author), de Kluijver, Wilbert (author), Helmons, R.L.J. (author), van Rhee, C. (author), Schott, D.L. (author)The traditional design approach of grabs and other bulk handling equipment consists of manufacturing and testing physical prototypes. A novel design approach is to use a co-simulation of MultiBody Dynamics (MBD) and Discrete Element Method (DEM), in which the virtual prototype of a new concept interacts with bulk solids. Therefore, this study...journal article 2021

Grashof, Bernd (author), Alvarez Grima, M. (author), Schott, D.L. (author), Helmons, R.L.J. (author)Rock cutting is a challenging process. Heavy equipment, large cutting forces, high wear rates and large amounts of required energy are common challenges when cutting rock. Traditionally, rock cutting is based on a linear motion of the cutting tool. However, a significant improvement on the cutting performance is expected when using non-linear...conference paper 2019

Helmons, R.L.J. (author)As a result of the worldwide population and welfare growth, the demand for energy (oil, gas and renewable sources) and raw materials increases. In the last decades, oil and gas are produced from more and more offshore sites and deeper waters. Besides energy, the demand for diverse metals and rare earth elements increases as well. These raw...doctoral thesis 2017
