Project Description

Danfoss has virtualized physical application development centers (ADC) to accelerate development of vehicle systems through simulation and modeling of engine, hydraulic circuits, work function kinematics, and vehicle dynamics. Students will develop semi-empirical tire models for real-time simulation of agriculture and construction machinery to enhance fidelity of the virtual ADC simulation of ground/tire interaction and vehicle dynamics. The main goal is the identification and implementation of a suitable semi-empirical tire model that takes tire flexibility into account and can be used as an alternative to the rigid tire model currently used in our 3D vehicle simulations. The first objective would be a literature study and analysis of the available tire models with a focus on off-highway vehicles. A second objective would be the implementation and test of one or several of the identified models as new ChronoTire classes (C++ coding). A third objective is implementation of optimization-based parameter identification routines to fit the underlying tire model parameters to real measurements. Students will also have an opportunity to operate a wheel loader that uses their model in Danfoss’ virtual ADC in Cambridge. Impact: Your model will be integrated to Danfoss’ virtual ADC and become part of a virtual test platform to accelerate vehicle design.
