Focus:
This article discusses requirements for system-level and component-level-simulation (and the relationships between the two) with an eye toward simulating electronic and electro-mechanical systems such as the drive train of a hybrid electrical vehicle (HEV), which is used an example. Within the context of component simulation, the article discusses the role of the finite element method (FEM) in solving equations where analytic solutions or series approximations do not exist. It then describes the boundary element method (BEM) and how it can reduce computation and modeling times for some problems. The benefits of BEM in an example application--a motor design--are discussed. With that as background, a process for performing component and system-level simulation of the HEV drive train is outlined. There is also discussion about the coupling of component and system-level simulation such as when a system simulator needs to "to call the FEM solver at certain time intervals". The example of a levitating disk is cited.
What you’ll learn:
- How to understand the roles and requirements of component- and system-level simulation in designing complex systems with electronics and electro-magnetic devices such as motors
- How to understand the process for performing component and system-level simulation in complex electro-mechanical systems such as an HEV drive train
