Experimental evaluation of the vibration efficiency of the general system of amortization of a diesel engine 2CH 8.5/11 with a hydraulic system mounted on a general supporting frame with toroidal wire rope vibration isolators
It is noted in the study that a steel cable by the structure is one of the most suitable materials used as a fire-resistant elastic element of vibration-insulating structures and absorbers (vibration insulators). To solve the problems of vibration isolation of ship diesel power plants, as part of the development and improvement of the shock-absorbing system, the original patented toroidal cable vibration absorber is presented. Evaluation of the vibration efficiency of the above mentioned vibration insulator was carried out by experimental studies as part of a common shock-absorbing system for 2 Ch 8.5 / 11 diesel engine with a hydraulic brake mounted on a bearing frame. When it is impossible to solve the problems of vibration in the machinery with known serial rubber-metal vibration isolators, the authors propose the use of vibration isolators with an elastic element made of steel rope, for example, with a toroid-shaped. Vibration efficiency of the latter is confirmed experimentally. To improve and develop such vibration insulator engineering designs, a special universal bench is designed, based on a diesel generator set with 2Ch 8.5 / 11 diesel, for not only supporting, but also non-supporting ties.
