Выполнен анализ параметров, характеризующих виброактивность объекта исследования и определяющих возможность его применения в составе определенной механической системы. Разработана программа испытаний, включающая в себя замер общих пиковых значений виброускорений на компонентах топливной системы, преобразование полученных данных при зависимости пиковых значений виброускорений от частоты вращения коленчатого вала двигателя и спектра частот вибраций, сравнение этих зависимостей с предельно допустимыми значениями, полученными в ходе испытаний компонента на вибростендах. Исследования выполнены на одном из наиболее напряженных элементов топливной системы Common Rail - датчике давления в топливном аккумуляторе RDS 4.2 производства компании Robert Bosch GmbH, устанавливаемом на двигателях ММЗ Д245.7Е4.</p><p>В соответствии с методикой испытаний измерения проводили на моторном стенде во всем диапазоне внешней скоростной характеристики двигателя. Результатом вибрационных измерений стала за пись пиковых значений виброускорения по времени в трех направлениях с каждого акселерометра и частоты вращения коленчатого вала двигателя.</p></abstract><trans-abstract xml:lang="en"><p>The objective of the paper is to develop a program, a methodology and execute vibration load tests of Common Rail fuel system components for a diesel engine. The paper contains an analysis of parameters that characterize vibration activity of research object and determine its applicability as a part of the specific mechanical system. A tests program has been developed that includes measurements of general peak values of vibration acceleration in the fuel system components, transformation of the obtained data while taking into account the fact that peak vibration acceleration values depend on crank-shaft rotation frequency and spectrum of vibration frequency, comparison of these dependences with the threshold limit values obtained in the process of component tests with the help of vibration shaker. The investigations have been carried out in one of the most stressed elements of the Common Rail fuel system that is a RDS 4.2-pressure sensor in a fuel accumulator manufactured by Robert Bosch GmbH and mounted on the MMZ D245.7E4-engines.</p><p>According to the test methodology measurements have been performed on an engine test bench at all fullload engine curves. Vibration measurements have resulted in time history of the peak vibration acceleration values in three directions from every accelerometer and crank-shaft rotation frequency.</p><p>It has been proposed to increase a diameter of mounting spacers of the fuel accumulator and install a damping clamp on high pressure tubes from a high pressure fuel pump to the fuel accumulator that permits to reduce a maximum peak vibration acceleration value on the pressure sensor in the fuel accumulator by 400 m/s2 and ensure its application in the given engine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вибронагруженность</kwd><kwd>вибропрочность</kwd><kwd>виброустойчивость</kwd><kwd>топливоподача</kwd><kwd>дизель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vibration load</kwd><kwd>vibration strength</kwd><kwd>vibration stability</kwd><kwd>fuel supply</kwd><kwd>diesel engine</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Системы управления дизельными двигателями / Robert Bosch GmbH ; пер. с нем. - М. : За рулем, 2004. - 480 с.</mixed-citation><mixed-citation xml:lang="en">Bosch.
