Abstract
The invention discloses a marine main engine base based on quiet technology and elastic damping. The marine main engine base comprises two sets of upper-layer supporting wrist plate assemblies, a lower-layer supporting wrist plate assembly and a plurality of elastic damping supports respectively arranged between each of the two sets of upper-layer supporting wrist plate assembly and the corresponding lower-layer supporting wrist plate assembly. Each upper-layer supporting wrist plate assembly comprises a bar-shaped panel, a plurality of upper-layer supporting wrist plates, a supporting angle iron and an upper vertical plate; the lower-layer supporting wrist plate assembly comprises two H-shaped sectional materials, a plurality of lower-layer supporting wrist plates, a plurality of external transverse bar plates and a plurality of external vertical plates. The marine main engine base based on quiet technology and elastic damping is compact in structure and convenient to manufacture, adopts modular design, and is wide in application range; when the marine main engine works, generated vibration is downwards transmitted to the supporting angle irons and the upper-layer supporting wrist plates through the bar-shaped panels, and finally most vibration is eliminated by the elastic damping supports. Vibration of the lower-layer supporting wrist plates is reduced, and thereby the purpose of reducing noise is achieved. Through tests, the marine main engine base based on quiet technology and elastic damping can achieve a 30% reduction in vibration, thus being significant in damping effect.
