Validating Nonlinear Transducer Motor Simulation with Measurement
New Paper: Comparing FEA simulations and measurements for nonlinear transducer motors
Our latest paper, “Validating Nonlinear Transducer Motor Simulation with Measurements,” opened the ISEAT conference and was very well received by an audience of around 300 participants. The study addresses the use of Finite Element Analysis (FEA) as a powerful tool for predicting the behavior of electro-dynamic transducers without the need for numerous physical prototypes, while also highlighting that the validation of FEA results remains a challenging and time-consuming task.
The paper highlights the application of a fast, full dynamic, and non-destructive measurement technique developed by KLIPPEL to validate a COMSOL-based FEA simulation of the position-dependent force factor (Bl(x)) and the frequency- and position-dependent lossy self-inductance (Zₗ(f,x)). The study compares the nonlinear motor parameters obtained from both measurement and simulation and further identifies which of these parameters are most critical for accurately predicting transducer behavior, particularly with respect to nonlinear distortion generation and voice coil stability.
