Research on the Annoyance Rate of Vehicle Vibration Serviceability

An important problem in current analysis method is that one can hardly know the exact structural design effects when using the conventional guidelines. In order to solve the problem, the annoyance rate analytical method suitable for vibration serviceability analysis of vehicle was constructed from a viewpoint of psychophysics, based on the existing basic method of methods and referenced to experimental studies at home and abroad. As an application example of annoyance rate method, a nonlinear vibrations system with two-DOF was built. The acceleration response of the vibration system under random loads of Gaussian distribution was analyzed with the new method. The result shows that the most important advantage of the annoyance-rate method is that it has the more quantitative characteristic and its results well coincide with those of the ISO method.
