An 8 degree-of-freedom (DOF) vehicle model is established to investigate the vertical vibration characteristics of an exhaust system excited by road surface inputs. The simplification of an exhaust system relevant to the vehicle model is discussed in detail, including the steps of exhaust modal analysis, definition of mass element, exhaust partitioning, parameter acquisition, and simplified exhaust validation. The vehicle model is developed based on a half-vehicle model, simulated using MATLAB/SIMULINK, and validated by comparing the simulation and experiment on various road profiles. Results show that the vehicle model effectively represents the dynamics of the vehicle characteristic in vertical vibration.

In order to study the vibration transfer characteristics of passenger car door, modal and vibration transfer function of passenger car door are simulated by using HyperMesh and Nastran synthetically. The accuracy of the finite element model is verified through modal analysis. According to the first two modes, the position of transfer function response points is confirmed. The vibration transfer functions are simulated and the accuracy of the simulation is verified by test. The research shows that the natural frequency of a passenger car door is not necessarily a pole of the passenger car door transfer function. On the contrary, a pole of transfer function is bound to be a natural frequency of the passenger car door, which is of directive significance to study the NVH characteristics of the passenger car door structure.
