摘要：The valve train plays an important role in the engine, which has a great influence on engine performance and reliability. In this paper, valve trains are studied based on multi-body dynamics theory and virtual prototype technology. Multi-rigid-body dynamic model of the valve train is established with Adams software, and then simulation and calculation are carried out. Dynamic characteristics of the valve train are obtained including force and motion of each component. The research results have important theoretical significance and practical engineering value in the design, dynamic analysis and optimization of valve trains.
