Respected peteroznewman,nI do not have a free choice in what to analyze.nMy Objective is to relate vibration data to Acoustic data and predict noise emitted by high-speed ball bearings.nMy purpose was extracting displacements, velocity data from a transient model. nI have velocity and acceleration data from simulations in Matlab. Can I input this data for getting sound pressure level emitted by ball bearings as the analytical equation for the same is not available (as per my knowledge, the equations (19) in Zhang, Q., Yang, J., & An, Q. (2018). Noise Calculation Method for Deep Groove Ball Bearing with Considering Raceway Surface Waviness and Roller Size Error. Frontiers in Mechanical Engineering, 4(October), 1–15. https://doi.org/10.3389/fmech.2018.00013) is dimensionally inconsistent.nI have tried Modal Analysis--> Harmonic response with the ACT plugin in ANSYS 18.0. Attached in the archive my project. nnI know this is a difficult task to model. Any help in this regard would be highly appreciated.nn
