TL;DR
This paper introduces a more accurate method for predicting vehicle door sealing forces using finite element analysis, reducing errors from model simplifications.
Contribution
A novel multi-boundary coupling simulation method using FE analysis to predict sealing system reaction forces with high accuracy.
Findings
The proposed FE method achieves a 7% mean absolute percentage error compared to experimental data.
A 75% increase in lock-side seal CLD results in a 22% increase in total sealing system reaction force.
The method accounts for coupling effects between the door and flexible seal, improving prediction accuracy.
Abstract
The accuracy of calculating the reaction force in vehicle sealing systems using moment equilibrium equations from statics is highly dependent on the degree of simplification in the mathematical model. This study demonstrates that employing the Finite Element (FE) method allows for a comprehensive consideration of the coupling effects between the door and the flexible seal, thereby eliminating errors inherent to model simplification and single-boundary variables. Consequently, this approach improves the prediction accuracy of the sealing system’s reaction force. In this work, a multi-boundary coupling simulation method for a vehicle door sealing system was established using the Finite Element (FE) method, which accounts for the interaction between the seal and the complex door structure. The results, based on data from three distinct vehicle models (with three doors tested per model),…
