In this article, a massless link model transmitting external forces is deve
loped to achieve numerical efficiency in simulation of vehicle suspension s
ystems. Forces acting on links are resolved and transmitted to attached poi
nts with a quasi-static assumption. Also, a theoretical derivation and comp
uter implementation of a massless link with bushing elements are proposed.
In the massless link with bushing elements, one end is connected to the adj
acent body by bushing, and the other end is connected by a spherical joint.
The deformation of a massless link with bushing elements is determined by
minimizing the potential energy function with a quasi-static equilibrium as
sumption at each time step. Several simulations with a full vehicle model a
re carried out to compare the efficiency of the developed massless link com
ponent. It is concluded that the proposed approach can reduce the computati
onal time enough to achieve a real-time simulation with a full vehicle mode
