Establishing a methodology of parallel computing which considers collaborative computation with other computer codes and/or softwares which may be installed in different computers is important for collaborative parallel computing with other softowares of multibody system which are developed under separate developing environments. In this paper, a fundamental parallel computing procedure is proposed by means of DAE approach in multibody dynamics. Then constraint errors in DAE are analyzed and a stabilization procedure of constrained errors is derived to be introduced into the proposed parallel computing procedure. By modifying standard DAE of multibody system, each subsystem is obtained by decomposing a total system into several subsystems so that parallel computation can be proceeded. The proposed method is effective for combining multibody subsystems which are developed in different developing environments. This paper describes a proposed procedure, and presents numerical simulation of a fundamental example to show the effectiveness of the proposed method.
