The track chain system consists of the track links and connecting bushings. There are two types of bushings.
A double pin track link is mainly used for a heavy and high mobility tracked vehicle. When two adjacent track links are connected by the double pin track link, the pin connector element has very small mass and mass moment of inertia, compared to those of the track links. Therefore, the dynamic effects of connector element are negligible. Therefore, the connector is modeled as a compliant element to reduce the number of degrees of freedom. The geometric information of the double pin track link is used for both display and contact force computation in the solver.
