This paper, based on a mini car, the interior noise analysis model is built from the viewpoint of transfer path analysis of the engine vibration energy, the transfer characteristic of transfer paths are discussed, the most important transfer paths and subsystems are identified. Based on ADAMS software platform, a parametric and dynamic model of mounting system is established,and the influence of the parameters of mounting system on vehicle interior noise is discussed. With the optimization objective of the lowest interior noise, the mounting system is optimized based on interior noise transfer analysis model. These can provide reference significance for design of powertrain mounting system.
