In order to choose the reasonable powertrain mounting locations, the finite element models of a certain type of engine block, transmission and powertrain were established, and their dynamic characteristics were analyzed separately. The results show that the middle mounting point located on flywheel is better than which on clutch shell. Engine vibration severity has decreased from 3.92mm/s to 3.20mm/s, and powertrain vibration severity has decreased from 4.13mm/s to 3.43mm/s by changing the mounting locations. The experimental validation shows that reasonable choice of powertrain mounting locations is useful to reduce engine vibration transmission and increase ride comfort.
