in Leaf Spring Damper
Recently, a new lateral vibration damper using leaf springs and oil, named as a leaf spring damper (LSD), developed by Jei and Kim. The major advantage of this novel damper is that the dynamic characteristics of the leaf spring damper can be easily controlled by the design of side clearance and leaf spring packs. Therefore, the leaf spring dampers can be useful for turbomacinery, high speed spindles, vehicle axles, etc. In additon, since the leaf spring damper can directly cooperate with rolling element bearings, it ultimately extends the usage of rolling element bearings by providing damping property.
The present paper have been investigated experimentally the dynamic characteristics of a lateral leaf spring damper with different side clearance and oil viscosity. Experiments were performed to investigated the effects of side clearance and oil viscosity on the damping of lateral leaf spring damper. The stiffness and damping coefficients are obtained from the displacements and the reaction forces generated by rotating the eccentric shaft. All dynamic coefficients are plotted with the excitation frequency which is adjusted by rotating speed of shaft. The test rig and two different leaf spring damper were manufactured to test the dynamic characteristics of the leaf spring damper.
