Topic: The Effect of Tolerances as calculated by Finite Element Analysis
During this presentation, a case will be discussed that is at the intersection between four subjects:
- Finite Element Analysis, in this case of:
- Electromagnetism, more specifically force of an electromotor
- Statistics of (pseudo)random numbers, in this case used for:
- Tolerances
Taking tolerances into account for a calculation usually leads to a small deviation from a nominal value, but sometimes an entirely new effect is found. A case will be discussed where the spectrum of vibrations, caused by an electric motor, shows new frequencies when manufacturing tolerances are included in the Finite Element Analysis.
The type of Stochastic Finite Element Analysis used here is called Monte Carlo. It is the most straightforward approach, where nominal values used in the calculation are replaced by random variates, drawn from a predefined random number distribution.
Some methods for achieving this will be discussed, abstract as well as very concrete.
