A Unified Transient EHL-Based Framework for Determining Contact Stiffness and Damping for Application in Spur Gear Dynamics
Time-varying mesh stiffness (TVMS) is a primary contributor to gear noise, vibration and harshness (NVH). Accurate implementation of the lubrication effect on the TVMS is often neglected. This work presents a numerical lubricated contact stiffness extraction method by combining the lubricant film and elastic compliance...
