Multibody Dynamics with Ansys Motion
Faster, further, quieter – learn how to efficiently simulate complex motion sequences.
When it comes to developing or improving complex systems, e.g., crankshafts, transmissions, or even entire power trains, questions relating to how well the system functions, the resulting loads, and derived properties such as smoothness or durability are often of great interest. ...

When it comes to developing or improving complex systems, e.g., crankshafts, transmissions, or even entire power trains, questions relating to how well the system functions, the resulting loads, and derived properties such as smoothness or durability are often of great interest. Transient processes like these are typically examined via multibody simulation (MBS, also multi-body dynamics, MBD). Ansys Motion provides the user with a high-end solution. This course has been specifically shaped to provide the kind of introduction to the program that will enable you to use the software in an efficient manner. Through the use of many practical examples, you will become familiar with the interface so you will soon be able to configure the right settings yourself.
Ansys Motion comes with its own preprocessor and postprocessor. The newly developed Workbench interface now provides the user with a powerful postprocessor in addition to the solver. During the course, the entire model setup and simulation will be performed in Workbench. Post-processing is carried out in Motion's own post-processor.
This course is aimed at simulation engineers involved in the development of complex, moving structures. It does not matter whether you already have experience in the field of multibody simulation or in simulation with Ansys or if you are a complete beginner. This course offers the perfect introduction to Ansys Motion and shows you the best ways to use it.
You will be enabled to build, solve and correctly interpret MBS models for the simulation of complex motion sequences. You will thereby leave behind the basic assumption that all bodies are rigid and learn how to consider flexible and therefore oscillating bodies. This will enable you to calculate bearing loads and requisite drive torques in the shortest possible time and also to uncover design deficits and kinematic constraints.
