Meet our team
Education: University of Applied Science - UtrechtDate of birth: 8 September 1965Nationality: NetherlandsWorking in the Railway industry from 1991. June 2014 I started my PhD study at Delft University of Technology, section of Railway Engineering (in part-time). The topic of my PhD research is the railway switch panel. Improving the reliability of switches will mean a lot for the performance of the railways. Beside my PhD I am working three days a week at the consulting company DEKRA Rail. I have specialised in vehicle-track / wheel-rail interface issues and from my role as business development manager I have direct technical and commercial contacts with our clients. Have become a recognized specialist in my field. I am experienced in managing large and complex projects e.g. responsible Project Manager of an European Research project with a large group of international partners from the Industry as well as Universities . Experienced in presenting for large audiences, having published my research for over 15 year and presented these papers at conferences all over the world.

SP2: Switch Panel Structural Performance. Materials innovation institute M2i project number T91.1.12475a
Railway switches, key elements in railway operation, are severely loaded by trains. Resulting damages lead to urgent and unplanned replacements, non-availability of track and high monitoring and replacement cost. The aim of this PhD study is to improve the structural performance of the switch panel (switch and stock rail) in terms of reliability, availability and maintainability, addressing the current industry needs. The research objective is to improve the understanding of the root causes of switch panel rail damage and potential mitigation measures and to develop improved engineering models to aid and design optimisation. June 2014 this PhD research started with a more in depth inventory of overall switch damage. Understanding the relationship between parallel research lines within the integrated project on switches at TUD a complementary research scope was defined. The research topic on vehicle-track interaction, identifying measures to decrease switch panel loading, was the first to be started, studying narrow curving behaviour. Investigating the optimisation of bogie rotation rigidity of trains by changing the suspension design between the wheelset and bogie frame, introducing suspension behaviour which depends on loading characteristics. Evaluating the potential of this design change to reduce wear and tear at the wheel-rail interface thus enhancing the so called ‘track friendliness’ of trains. Assessment of vehicle running behaviour was carried out by means of vehicle-track simulations within the VAMPIRE multi body simulation software. At the wheel-rail interface the impact of the suspension design modification is quantified in relation to the wear, rolling contact fatigue (RCF) damage, vehicle stability and passenger ride quality. Simulation results assessing classic curving behaviour clearly showed the potential the proposed measure through a significant reduce in wear and contact fatigue loading. From this first work fisrt full conference papers and a scientific article have been delivered. Preparation of a field test program regarding track friendliness has been carried out, together with setting-up further switch panel track models using the simulation software tool VAMPIRE to allow evaluation of switch panel vehicle negotiation. Furthermore foreseen in 2016 is to start researching on switch panel rail material optimisation. Dissimination of results through full conference papers and scientific articles.
