Constraint stabilization of deployment simulation for deployable trusses

In this paper, a geometric elimination is interpreted by using Tailor's series and Moore Penrose inverse, a new technique to stabilization constraint violation is developed for deployment simulation of deployable truss based on Soon' theory of. A simple technique is employed to correct the system energy violation. The modified geometric elimination can combine with any numerical integration algorithm. The examples show the technique has a high precision. To obtain an accurate result, the energy stabilization should be combined with geometric stabilization.
