Research Assistants (AR) - Mechanical design and machine construction (Prof. Concli, Franco)The Free University of Bozen/Bolzano was founded on 31 October 1997 as a multilingual, internationally oriented institution.Deadline for sending applications: 11.12.2024 at 12:00 PM (noon)Description of the research activity:The main goal of the project is to develop and validate a method to predict the kinematics of each bearing component considering contact and hydraulic forces, i.e., an improved LaMBDA model integrated with hydraulic forces.
To achieve this main goal, the following sub-goals need to be met:A Design of Experiment (DoE) that enables the exploration of several operating conditions within the constraints of project resources has to be defined, including the main parameters influencing hydraulic forces.A CFD model capable of calculating the hydraulic forces on each bearing component under the operating conditions established in the DoE has to be developed.A database of hydraulic forces as a function of the DoE parameters has to be built by exploiting the CFD simulation results.An experimental campaign testing the operating conditions delineated in the DoE has to be performed to measure the kinematics of the bearing components, the operating temperature, and the overall resistant torque due to hydraulic forces.The CFD model has to be validated by comparing the numerical and experimental results in terms of hydraulic torque.A methodology for integrating the hydraulic forces within LaMBDA has to be developed to fine-tune an improved version of LaMBDA capable of considering both contact and hydraulic forces.Kinematics resulting from the newly developed methodology have to be compared with experimentally measured kinematics to validate the final research result and quantify the accuracy improvement achieved.Job detailsTitle: Research Assistants (AR) - Mechanical design and machine construction (Prof. Concli, Franco)Published: 2024-11-25Application Deadline: 2024-12-11 12:00 (Europe/Rome) #J-18808-Ljbffr
