Aerodynamic vibration analysis coupled by fluid analysis of internal HDDs

The influence of aerodynamic excitation and the structural vibration analysis of arms and disks based on the excitation force that can be calculated by airflow analysis are evaluated. Then, a very easy-to-use system to calculate airflows and to follow up with evaluating vibration characteristics of internal structural bodies in HDD is developed. Airflow calculation is based on direct numerical simulation; therefore, actual fluidic phenomenon is reproduced.
