| Abstract: | This paper researched the modeling and vibration characteristic of the hydraulic excavator's powertrain mounting system is a whole body condition.Using the ADAMS,a 12-degree-of-freedom(DOF) model was set up which contained both the powertrain and the whole body.The system mode and the vibration characteristic of the 6-DOF model were compared with those of the 12-DOF model by the simulation,and the system vibration transfer ratio of the 12-DOF model was obtained.The results show that the 12-DOF model is more... |
