dc.description.abstract	Accurate inertia parameters of a heavy truck cab, including the mass, the position of mass center, the moment of inertia and the product of inertia, and so on are basic parameters for whole vehicle dynamic analysis. A domestic heavy truck cab was focused. The frequency response functions (FRFs) were obtained by LMS data acquisition system. The center of mass in the XY plane of the cab was obtained by the weighing method. On the other hand, the center of mass of the cab was calculated based on the mass line, extracted from the FRFs.

Abstract:

Accurate inertia parameters of a heavy truck cab, including the mass, the position of mass center, the moment of inertia and the product of inertia, and so on are basic parameters for whole vehicle dynamic analysis. A domestic heavy truck cab was focused. The frequency response functions (FRFs) were obtained by LMS data acquisition system. The center of mass in the XY plane of the cab was obtained by the weighing method. On the other hand, the center of mass of the cab was calculated based on the mass line, extracted from the FRFs. Both results were compared and show that the error in X direction was 1.99 cm and the error in Y direction is 0.68 cm. It is concluded that the mass line method is of good measurement precision. Then the moment of inertia, the product of inertia, the principal moment of inertia and the principal axis direction were calculated successively. The reasons of errors were analyzed and discussed.
