Device for simulation of vibrations and internal combustion engine test bench comprising the same

摘要

Exhaust line vibrations simulation device has an adjustable valve (14) to control the rate of exhaust gas for simulating loss of charge induced by an exhaust line. An assembly of three passive mechanical systems (20) has mass-spring-damper (M-K-C) sub-assemblies (25) reproducing vibrations of the line and is connected on a disconnection unit (11) integrated to an internal combustion engine (12). The assembly is adjusted for simulating the vibrations.
