Original abstract

This article presents a computational approach for prediction of excitation of vehicle body near the powertrain mounts. A Multi-Body System (MBS) is used for simulation of this problem, where powertrain is built as all-in-one model and transmission of torque from crankshaft to a vehicle wheels is incorporated. Therefore, this approach requires modelling of complete powertrain, including a final drive and drive shafts. The transmission of vibration from a powertrain to a vehicle body is realized by computational model of powertrain mountings system and simulation results are compared with data obtained by experiment at a passenger car vehicle with three-cylinder spark-ignition engine. The main aim of this article is a description of influence of different types of MBS model complexity on accuracy of simulation results, description of basic computational model of powertrain mounting system and a suggestion for mounting system optimisation during design process phase.

Czech abstract

Článek představuje možnosti výpočtového modelování buzení karoserie vozidla v blízkosti lůžek pohonné jednotky. Simulace jsou prováděny v prostředí MBS (Multi-Body System) na modelu celého hnacího řetezce vozidla, včetně stálého převodu a hnacích hřídelů. Přenos vibrací z pohonné jednotky na karoserii je simulován pomocí výpočtového modelu lůžek a výsledky jsou porovnány s experimentem na vozidle s řadovým tříválcovým zážehovým motorem. Hlavním cílem tohoto článku je popis vlivu různé úrovně MBS modelu na přesnost výsledků simulace, popis základních výpočtových modelů lůžek a návrh optimalisace těchto lůžek v průběhu vývoje pohonné jednotky.
