Effects of Constrained-Layer Damping on the Dynamics of a Type 4 In-Line Head Suspension

Henze, Dick; Karam, Ray; Jeans, Albert



Abstract: Experimental frequency response functions were obtained for several Type 4 in-line suspension assemblies with lateral excitation. Mode shapes are described for all the modes observed between 1 and 15kHz. The effect of a constrained-layer damper on several of the most important modes is described. The mechanism of the lateral bending or sway mode is explored to explain the reduced effectiveness of the damper for this mode.
