Emulational simulation of valve train based on rigid-flexible coupling model

By adopting the idea of firstly building the entity model, then introducing it into ADAMS to build a multiple-rigid-body model, and at last replacing part of the components with the finite element model, the rigid-flexible coupling dynamic analysis model for the valve train of a certain type of diesel engine is set up. Meanwhile, the dynamic simulation analysis on the model is made, and the analysis result coincides with related test data, showing that precision of the model is higher. The analysis result can be made as the reference for the design improvement.
