    In this study, a two-dimensional High-Static-Low-Dynamic-Stiffness (HSLDS) system is proposed using a combination of simple springs. The theoretical formulations of the HSLDS system are developed, and the spring parameters are optimized to maintain stability and achieve low dynamic stiffness within the designated workspace. The designed HSLDS system is applied to a rotating system to evaluate its effects on whirling responses. The results clearly reveal that whirling responses with HSLDS bearings are reduced by over 75% due to the system’s low dynamic stiffness and enhanced damping ratio. Experimental validation confirms that the HSLDS bearings effectively reduce whirling, aligning well with the theoretical predictions and supporting their practical applicability.
