Abstract
The Parking system of Automatic Transmission(AT) has several mechanical parts to keep stopping vehicle safely in the parking position. When select lever is moved from R to P, vibration is occurred by contact between two parts in the parking system. Then such vibration is transferred to driver as interior noise throughout AT case and select lever. In this study, We have developed a simulation method by using multi-dynamic analysis and modal transient response analysis. At first we made dynamic model to calculate contact force which became the source of excitation. Then we made Finite Element(FE) model for calculating normal mode analysis and transient response analysis. We performed experiment in order to validate simulation. We found out that simulation results have a good correlation with experiment. This simulation method will help to shorten the development period and cost.
