Study for Prediction the Door Checker Effort by using 2D-Contact

Abstract

With the development of the automotive industry, people are eager for better vehicle capability. One of them is the door opening and closing performance. Proper door effort opening and closing a vehicle can insure safety for passenger and pedestrian, while ensuring door operating convenience. Since checker effort is the important design parameter to determine door performance, analysis for a vehicle door checker effort is one section in early design with the door. In order to predict checker effort more accurately and rapidity for engineering applications, this thesis developed a new algorithm, applying the 2-dimension method to analyze the model by using dynamic analysis software DAFUL. Finally, this 2-dimension method has been verified with the comparable results between the analysis results and experimental results.
