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.
