Research Fields
1. Different with conventional works, a turbocharger compressor under combined centrifugal and interference-fit loading is used for the numerical analysis. On the basis of parametric variational principle (PVP), the analysis of the impeller-shaft sleeve-shaft elastic and elastoplastic frictional contact problem is performed. Gyroscopic systems can be guided to Hamilton systems which construct a perfect theoretical frame. Based on the characteristics of rotor dynamics, an adjoint symplectic subspace iteration method is applied to turbocharger rotor dynamics. This methodology is different from the traditional ones and is used to study the nonlinear mechanics problems of turbocharger from a new viewpoint.
2. Taking a certain type of metro vehicle bogie frame as the research object, according to the basic principle of modal synthesis method, the frame modal neutral file have been get through the modal analysis of the frame by free degree reduction. The rigid flexible coupling multibody dynamics model is set up by using the neutral file. Finally, combined with the material S-N curve, fatigue life of the key parts of the frame have been predicted by the method of virtual fatigue simulation.
