Originální abstrakt

The mounting system of a vehicle powertrain has to meet many demands on durability, powertrain weight support and support of the powertrain torque, good isolation of high-frequency vibrations originating in the powertrain, damping of road induced vibrations and also crash performance. Therefore, experimental studies still have an irreplaceable role in design process of the mounting system, especially because it is a component involving rubber-like materials with many sorts of difficulties for computational simulation due to its nonlinear complex static and dynamic characteristics. But physical prototyping and testing is highly time-consuming and expensive process, so using of simplifying and accelerating testing methods is highly required. This article describes influence of two cases of the powertrain mounting method on vibration of both sides of powertrain mounting system (in front of the mount – the engine side (active side), and behind the mount – the chassis side (passive side)), whereas first case is powertrain assembly in a test rig (powertrain dynamometer) and second one is powertrain mounted in a car (chassis dynamometer). The experiment was carried out on a small passenger car powertrain with three-cylinder spark-ignition engine.
