Modeling of linkers in complex multibody system with transfer matrix method

On the basis of the theory of computational dynamics of multi-body systems,the transfer matrix was introduced to model the linkers in complex multi-body systems.As an example,the support bolt engine block was modeled and analyzed using the method proposed.The result shows that the modeling and analyzing method is feasible.On the premise of keeping the integral dynamics characteristics of complex systems unchanged and maintaining the linker's transfer characteristic properly,the method has the advantages of fast speed in achieving solution and small data size in calculation.The modeling method gives a foundation to establish the rapid assessment model of integrative diesel's vibration and impact.
