- Abstract:
- In this paper,a bus powertrain of which the structure and material are more complex is applied asan example. First,it introduces the inertial parameter identification technique based on experimental modal a-nalysis. The method obtains the center-of-mass coordinate and the inertial parameters of the powertrain throughthe excitation and the coordinate of response points,relative motions and dynamics equations. Then,the paperproduces how to obtain the inertial parameters of the powertrain on the basis of knowing the data of each part,it validates the accuracy of obtaining the complex inertial parameters of the rigid body through the contrast andanalysis with the result of experimental modal.
