The vehicle or drive mechanism is responsible for the transfer of energy from the engine to the wheels. Many of its issues in noise, vibration and harshness (NVH) only arise late in the design chain when all components are checked together in a wide range of circumstances. To alleviate the phenomena, few changes can be made without very costly palliative solutions. The only viable alternative is to configure clutch parameters once this engine and transmission are set in early stages to satisfy power and torque modulation requirements. In technical studies, the effect was shown to be highly influential on dynamic drivetrain behaviour, including laminated steepness and hysteresis. The gear shaft is an effect caused by induced noise of the unloaded gear pairs. In low- or idle-speed diesel engines like buses and trucks in traffic jam and in a more specific manner, it is diagnosed with a higher intensity when a resonance is excited for the entire drive system. The creation of low-rattle vehicles also helps to reduce noise pollution in cities in general. In this study the picture of the clutch found in literature will be evaluated and numerical integration evaluates the response of the torsional model. Results of simulations that change clutch parameters are tackled against changing properties of other system elements such as flywheel inertia, gear reaction and gearbox damping parameters so that it can be verified what plan to determine in a lower gear rattle stage.
