摘要：

A method of elimination of violations of both geometric and energy constraints for multibody system simulations was developed. The state variables are corrected after each integration step without any modification in the governing equations. While the exact elimination of violation of position constraints may require few iterations, the violation of velocity constraints and the violation of energy constraint are removed in one step.
