【Abstract】 Contact,impact and friction may induce none-smooth behaviors on velocity level for multi-rigid-body system.Variable structural dynamics can deal with them by loading and uploading constraints on the system.Variable structural dynamics for two dimensional dynamic system including contact,impact and friction is introduced.A 2D rod is presented to achieve the final dynamic simulation.更多还原
