Cai, Jie (author), Jiang, X. (author), Yang, Yazhou (author), Lodewijks, Gabriel (author), Wang, Minchang (author)A corrosion defect is recognized as one of the most severe phenomena for high-pressure pipelines, especially those served for a long time. Finite-element method and empirical formulas are thereby used for the strength prediction of such pipes with corrosion. However, it is time-consuming for finite-element method and there is a limited...journal article 2022

van Doorne, Mark (author), Lodewijks, G. (author), Beelaerts van Blokland, W.W.A. (author)The Automated People Mover (APM) is an important asset for many airports to transport passengers inside or between terminal and satellite buildings An APM system normally runs on fixed schedules throughout the day, which means that the capacity of the APM is pre-determined and not depending on the actual demand. This at times can cause either an...conference paper 2019

Alemi, A. (author), Corman, F. (author), Pang, Y. (author), Lodewijks, G. (author)Wheel impact load detectors are widespread railway systems used for measuring the wheel–rail contact force. They usually measure the rail strain and convert it to force in order to detect high impact forces and corresponding detrimental wheels. The measured strain signal can also be used to identify the defect type and its severity. The...journal article 2019

Alemi, A. (author), Corman, Francesco (author), Pang, Y. (author), Lodewijks, Gabriel (author)A wheel impact load detector is used to assess the condition of a railway wheel by measuring the dynamic forces generated by defects. This system normally measures the impact force at multiple points by exploiting multiple sensors to collect samples from different portions of the wheel circumference. The outputs of the sensors are used to...journal article 2019

Cai, J. (author), Jiang, X. (author), Lodewijks, G. (author), Pei, Zhiyong (author), Zhu, Ling (author)The ultimate strength of metallic pipelines will be inevitably affected when they have suffered from structural damage after mechanical interference. The present experiments aim to investigate the residual ultimate bending strength of metallic pipes with structural damage based on large-scale pipe tests.

Lommen, S.W. (author), Mohajeri, M. (author), Lodewijks, G. (author), Schott, D.L. (author)Purpose: The development of bulk material handling equipment can be accelerated and made less expensive when testing of virtual prototypes is adopted. However, the modelling of a grab unloader requires a large volume (77 m3) of iron ore pellets, making the computational costs prohibitive. This paper investigates the extent to which the...journal article 2019

Hu, Q. (author), Wiegmans, B. (author), Corman, Francesco (author), Lodewijks, Gabriel (author)This paper investigates the problem of inter-terminal movements of containers and vehicles within a port area in order to achieve an integrated and effective transport within the port and towards the hinterland. Containers from different port terminals are first moved to a rail yard and then delivered to the hinterland by rail. To provide...journal article 2019

Hu, Q. (author), Wiegmans, B. (author), Corman, Francesco (author), Lodewijks, Gabriel (author)Nowadays, the major ports around the world usually consist of multiple terminals and service centers which are often run by different operators. Meanwhile, inland terminals have been also developed to reduce port congestion and improve transport efficiency. The integrated planning of inter-terminal transport (ITT) between the seaport and inland...review 2019

Alemi, A. (author), Pang, Y. (author), Lodewijks, G. (author)Wheel defects are detrimental for railway train and track components and should be detected and identified as early as possible. Wheel Impact Load Detector (WILD) is a commercial condition monitoring system used for detecting the defective wheels. This system usually measures the rail strain at different points by multiple sensors. WILD converts...conference paper 2018
