Rigid and flexible multibody dynamics simulation analysis for the valve train of gasoline engine is conducted on the basis of the different constraints conditions, which among components have been varied in accordance with the kinematic and dynamic characteristics of the system to gradually approximate actual working conditions. Based on Lagrangian equation,absolute Cartesian coordinate and the floating frame of reference formulation for multibody dynamics, the computational dynamic simulation method used in professional simulation approach within computer program of UGNX is employed hereby to compute the displacement curve, velocity curve and acceleration curve of intake valve and exhaust valve, which elaborate the feature of valve motion, dynamic properties of the parts and whole system. Simulation results illustrate that computational dynamics of multibody system is an effective approach to analyze the dynamical characteristic of complex mechanical system in the flexible multibody model on the way of being high fidelity of the real constraints and load conditions of complex mechanical system with the consideration of all nonlinear factors arising from contact and impact constraint, flexible deformation of components and valve spring with designed parameters.
