Control of Damping Forces by Side Clearance in Leaf Spring Damper

겹판스프링댐퍼에서 측면틈새에 의한 감쇠력 조절

This paper describes that the leaf spring damper(LSD) developed by authors can be controled by side clearance between side cover and leaf spring. The test rig and two prototype dampers with different side clearance were manufactured. Experiments were performed to investigate the effects of side clearance on the damping of 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 coeffficients are plotted with the excitation frequency which is adjusted by rotating speed of shaft.
