The computational speed of multibody dynamic analysis depends on the number of bodies and constraints and the eigenfrequency of the system to be analyzed, and it is necessary to enhance the computational efficiency to realize real-time analysis of a large size system or of high frequency phenomena. In this paper, the computational efficiency of real-time multibody dynamic analysis was improved with matrix library. The matrix libraries were embedded to real-time multibody dynamics code developed by authors, and the computational efficiency among matrix libraries were evaluated on xPC Target environment. We evaluated the performance of matrix libraries with vehicle dynamic analysis. To investigate the relation between the performance of the matrix libraries and the sparsity of coefficient matrix, multibody vehicle models were modeled in two ways. The evaluation test were conducted with these models, and the computational efficiency was compared.
