Peugeot Citroen noise and vibration optimization for gasoline engine
TU5JP engine is currently used for a variety of platforms, including vehicles manufactured DOG successful "Super mini" class car, the Citroen Saxo. Block, head and transmission were built mainly of hexahedral elements, while the lowest accessories is modelled using a combination of elements of the highest ctyrboká, shell and beam, where appropriate. The technical approach in detail Here is the representative Ricardo is the standard methods used for the analysis of the driving to optimize its characteristics of noise and vibration. A modal analysis, dynamic load calculation, waking the load acting on the engine were calculated using ENGDYN. ENGDYN is used to predict the time domain response of vibration system tied 3dimenzní handles and cylinder block to train non-linear oilfilms in each of the main journal bearings. The forced response of acoustic analysis. basic patterns and difference chart compares the two. These data show a slight improvement as a result of this change. The outer ribs on the side of the drive shaft of the engine.
