| 中文摘要: |
| 介绍基于汽车油箱振动噪声控制的隔振优化设计。根据油箱和车身动刚度实测数据及振动传递损失率要求，确定油箱隔振垫静刚度的设计目标值为50 N·mm-1；利用仿真分析得到油箱隔振垫结构优化方案，并进行样件的单品静刚度测试，对比分析设计的准确性。整车NVH测试结果表明，油箱隔振垫结构优化后隔振效果较好。 |

| The optimization design of vibration isolation based on the noise control of the fuel tank vibration of vehicle was introduced. According to the measured data of the dynamic stiffness of the vehicle body and fuel tank，and the requirement of the vibration transmission loss rate，the design target value of the static stiffness of the fuel tank vibration isolation pad was determined to be 50 N·mm-1. The structural optimization scheme of the fuel tank vibration isolation pad was obtained by simulation analysis，and the static stiffness was measeured in order to analyze and confirm the accuracy of the design. The vehicle NVH test results showed that the vibration isolation effect was better after the structure optimization of the fuel tank vibration isolation pad. |
