SimGroan - Simulation on Creep Groan Noise Investigation of excitation mechanism for FEM simulation using experimental data

Systematic investigation of the low frequency creep groan noise using experiments on the brake and suspension test-rig at FTG Determination of influencing parameter: temperature, humidity, brake pressure, stiffness of suspension parts (wheel carrier, caliper), brake pad material, rubber bearing, FEM simulation / investigation of excitation mechanisms Investigation of model and solution parameters for CEA (damping, contact stiffness, ) Comparison of solution methods for transient analysis: (complex modal base, direct frequ. domain, implicit & explicit time domain integration .) Examination of explicit time domain integration for application to stick-slip effects Preparation of simulation method and excitation data
