| 中文摘要: |
| 针对某车型在关门时车内出现的振颤异响问题，识别车内异常噪声产生原因为关门产生振动激励，经车身和安全带支架传递至卷收器，并引起卷收器内部异响。建立了车身和卷收器的系统动力学模型，分析了卷收器安装支架对振动传递特性的影响。完成了卷收器单体响度随激励频率的测试，并获得了卷收器单体的敏感频率。通过合理设计卷收器安装支架刚度，将振动传递峰值与卷收器敏感频率避开，有限地改善了异响问题，为同类问题的分析和优化提供了参考。 |
| 英文摘要: |
| In response to the issue of vibration and abnormal noise in the interior of a certain vehicle model when closing the door, it was identified that the cause of the abnormal noise was the vibration excitation generated by closing the door, which was transmitted to the retractor through the body and seat belt bracket, and caused abnormal noise inside the retractor. A system dynamics model of the vehicle body and the retractor was established, and the impact of the installation bracket of the retractor on vibration transmission characteristics was analyzed. Completed the testing of the loudness of the retractor with sweep excitation, and obtained the sensitive frequency of the retractor. By reasonably designed the stiffness of the installation bracket of the retractor, the vibration transmission peak is avoided from the sensitive frequency of the retractor, and the problem of abnormal noise is significantly reduced, and it provides a reference for the analysis and optimization of similar problems |
