Modeling and simulation of multibody systems in engineering fields becomes a standard and essential step in a design procedure. In vehicle dynamics. the modeling technique is important to achieve the computational efficiency and accuracy. When components with very small masses and great forces are contained in the modeling. the frequencies of the components become high. As a result. the efficiency of the simulation could be decreased. If effects of small masses can be ignored in the system. the simulation will be carried efficiently by eliminating the high frequency components of the motion. In this paper. a massless link concept which only considers kinematic relations of bodies is combined with force elements. The idea is explained and tested using several examples.

A vehicle dynamic analysis program AutoDyn7(Automobile Dynamics in G7) is developed in the G7 project. The AutoDyn7 program has several user-friendly subroutines, i.e., suspension module, road module, and leaf spring module. In this paper, the general structure and usage of the program are explained with several examples.<br/>
