Stage: Ansys Motion

One of our fields of interest is structural analysis. Using such analyses, one can for example calculate strength and stiffness to evaluate the performance of machines. The topic of this internship is flexible multibody dynamics, in  combination with co-simulation. This entails analyzing structural dynamics of a virtual machine, while its motion is controlled in a software package. A new program of Ansys called Motion is capable of this.

The goal of this assignment is to understand and test the accuracy and limitations of Ansys Motion. To this end, you will model and simulate one or more flexible multibody systems with increasing complexity. Ansys Motion offers several methods to perform this type of modelling (nodal, modal with normal modes, modal with static correction modes). A possible outline of the assignment could be:

• Explore in-depth the different methods Ansys Motion offers to model flexible multibody systems
• Come up with test cases that can be used to determine when each method is the suitable option to use
• Model and simulate these test cases 
• Benchmark each method in relation to standard Ansys in terms of accuracy, simulation time and meshing

• Education level: Masterstudent
• Education: mechanical engineering
• Preferably, you followed the course: ‘flexible multibody dynamics’
• Duration internship: 3 months
