The present paper introduces a new lateral vibration damper using leaf springs and oil. This damper, named as a leaf spring damper (LSD), has several beneficial rotordynamic advantages. The leaf spring vibration damper, unlike the well-known squeeze film damper, is simple and easy enough to design the required stiffness and damping coefficients. Furthermore, the damper can be designed as a unit product joined with a rolling element bearing. A theoretical modeling procedure for leaf spring damper is presented in detail. Prototypes of the leaf spring damper are manufactured to test the dynamic characteristics of the damper. Experiments are performed to measure the stiffness and the damping coefficients of the damper.
