Abstract
A engine-generator set includes a generator for producing electricity and an engine that is coupled via flexible coupling to a shaft of the generator for driving the generator, the engine being supported against a support surface by a plurality of resilient mounting elements, and the generator being supported against a support surface by a plurality of resilient mounting elements separately from the engine, wherein the engine is mechanically connected to the generator solely via the flexible coupling.
Claims19
An engine-generator set comprising:
- a generator for producing electricity;
- and
- an engine that is coupled via a flexible coupling to a shaft of the generator for driving the generator, wherein the engine is supported against a support surface by a plurality of resilient mounting elements, and the generator is supported against a support surface by a plurality of resilient mounting elements separately from the engine, wherein the engine is mechanically connected to the generator solely via the flexible coupling;
- wherein the resilient mounting elements of the engine and the generator are configured so that 1.2<fgen_vert/feng_vert<30, where fgen_vert is a natural frequency of vertical oscillations of a mass-spring system formed by the resilient mounting elements of the generator and a mass supported by said resilient mounting elements, and feng_vert is a natural frequency of vertical oscillations of a mass-spring system formed by the resilient mounting elements of the engine and a mass supported by said resilient mounting elements.
