Vibration and acoustic behavior of the internal combustion engine is very complex, consisting of many components that are subject to a large load is very varied and that operate at different speeds. TU5JP engines currently used for a number of vehicle platforms produced by the PSA, including the successful “Super Mini” class cars, Citroen Saxo. Blocks, heads and transmission of the most established low-order hexahedral elements, while the ancillaries modeled using a combination of a high order tetrahedral, shell and beam elements in a suitable place. Detailed technical approach here is representative of the standard method applied to the analysis Ricardo powertrain to optimize noise and vibration characteristics. Analysis of capital, Dynamic Load calculations, the excitation load acting on the engine is calculated using ENGDYN. ENGDYN used to predict the time-domain responses from the 3-dimensional vibration of the crank plus train and cylinder block system with non-linear oilfilms in each of the main bearing journals. Response force and Acoustic Analysis. basic design and compare the two different diagrams. These figures show the increase is negligible because of modifications.
