Nowadays, there are little ot researchers interested in kinetic with constraint problem. Additional, it is not easy to solve the kinetic with multi degrees of freedom with constraint problem by handing. In pact that, there are a lot of software to simulate motion of mechanical systems as Catia, Solidworks, TopSolid, Pro Engineer... but its only help solvers to observe motion of mechanical systems without acting simulating results. Therefore, the solvers could not use that software to simulate results of mechanical systems with constraint problem. So that, this research presents a method to solve and simulate mechanical systems with multi degrees of freedom with constraint problem.
