Tool Purpose & Background

Purpose of This Tool

This tool estimates the structural natural frequencies of flat rectangular plates and cylindrical shells (rings). It is especially useful in the context of eNVH (Electrified Noise, Vibration, and Harshness) analysis for electric motor design. By checking the natural frequencies of motor housings or inverter covers, engineers can avoid structural resonance driven by electromagnetic excitation frequencies (like the spatial orders from motor pole/slot combinations).
