Many aspects influence railway vehicle dynamics. One common aspect is the track defect, as the condition of the rail itself will interact directly with the wheel of the train when passing the rail. Dipped rail joint, which is practically impossible to eliminate its existence from the entire track, is the common track defect. The correlation between dipped rail joints with the vehicle response dynamics will help to have a better understanding to ensure safety and passenger comfort when the train is passing the dipped rail joint. While dipped rail joint was developed using MATLAB with different length and depth, dynamic simulation was performed using Universal Mechanism software to obtain quantitative data that represents the train dynamic response in the form of vertical acceleration of the train. The analysis was conducted using several parameters to see the effect of dynamic response due to dipped rail joint. The dyanmic response due to dipped rail joint changed as changes in several parameters occurs, e.g. dipped rail joint with depth of 2.5 mm resulting in a response with amplitude of 1 m/s2 and if the depth is increased to 5 mm the amplitude of the response is 2 m/s2.Therefore, a better understanding of the relationship between dipped rail joint and the changes in parameters, will enhance the dipped rail joint detection and monitoring process in the future.
