WebThe SHAA and SHAB rubber and spring vibration isolation hangers are designed to provide high-efficiency isolation from structure-borne vibration for lighter point load applications. It is important the spring is adequately loaded to achieve the desired natural frequency. The SHAA provides 1" (25 mm) deflection at loads of 17 to 71 pounds (8 to ... WebAn archetypal structure-borne sound problem is illustrated in Fig. 10.7(a).A known vibrational force excites structural vibration in one component. Vibration is transmitted to other components, which radiate sound. In Fig. 10.7(b) the excitation takes the form of an inexorable velocity excitation. This duality of source representation emphasizes the fact …
