“…These sensors are calibrated by the terminal operator on a regular basis. Kinematics of geometry: to record kinematics of the grab geometry, a video tracking technique similar to [7] is used. Basically, the grab geometry consists of two rigid bodies that revolves over a main hinge.…”

“…force in cables, torque in winches) are compared between the experiments and simulations using the coefficient of determination, R 2 , as described by Weisberg [40]. To validate the force in cables and the torque in winches, Lommen et al [7] suggested that minimum R 2 values of 0.9 and 0.8 are required respectively.…”

“…The small error is probably caused by idealizing the bulk surface in the simulation and its operational characteristics. Also, Schott et al [7] have validated the simulation of the grabbing process of free-flowing iron ore products with values of |e| 6.0%. Therefore, the payload values for test 1 are simulated adequately, compared to reality.…”

“…Lommen et al [5] have developed a real-scale co-simulation between grabs and free-flowing iron ore material [6]. The co-simulation has been validated for simulating the grabbing process of iron ore pellets [7]. As shown in Fig.…”
