Vibrational Performance Optimization of a Commercial Vehicle through CAE and Test Methods Combination

Vibrational Performance Optimization of a Commercial Vehicle through CAE and Test Methods Combination

Cury, Davi Machado; Nardelli, Fernando Henrique; Oliveira, André de;

Artigo:

The root cause of the vibrational problem of a vehicle can be attributed to different sources and vehicle subsystems, depending on the vibration phenomenon and its frequency range. Powertrain mounts, chassis damping elements and upper body structural flexibility all play a major role and must be considered in both CAE and test for a reliable analysis. Also, the vehicle model must include representation not only of the dynamic properties of its subsystems but also of the excitation inputs (road profile, engine internal loads). Hence, better prediction levels can be reached by using data measured during the test campaign to populate the virtual model.
