Abstract:Asphalt drum dryers are of foremost importance in the production and recycling processes of asphalt. The drum dryers include a steering system that carries and rotates the drum. The main function of such steering system is to manually align the drum in order to minimise wear and prevent drum translation during operation. However, the manual alignment is relatively inaccurate and often leads to significant wearing of the steering system components. Accordingly, the objective of this MSc assignment was to redesign the drum dryer steering system such that component wear is reduced. An Engineering Design Process was applied following the Pahl & Beitz methodology and includes specific Systems Design Tools and Methods. Firstly, research was performed on subjects like contact mechanics and afterwards, the former steering system design was evaluated in detail to distinguish the failure modes with their severity. Consequently, a measurement method was designed to validate the determined internal forces in the former steering system. Thereupon, the design phase started with creating morphological analyses and concepts after which a final concept was chosen as the base for the proposed steering system design. Such design includes an automated sensory angle correction mechanism to minimise misalignment. By the end of the assignment, the design requirements were met but the performance of the steering system design still needs to be verified since no experiments could be performed on the design yet.
