| 摘 要： | 与传统的最小二乘复指数识别(LSCE)法相比,多参考最小二乘复频域(LSCF)法既适用于弱阻尼也适用于强阻尼密集模态系统的识别。针对某轿车用195/65R15 91V型Hankook轮胎,采用LSCF法与LSCE法进行了轮胎试验模态分析。对比结果表明,LSCF法在低频区域尤其是在模态较密集的中高频区域所提取的模态均能很好的满足模态验证准则,具有LSCE法不可比拟的优势。

| Abstract: | Compared to the traditional LSCE method,the multiple input Least Squares Frequency Domain method(the LSCF method)not only applies to weak damping but also the identification of heavy damping mode system.Applying LSCF method and LSCE method to analyze tire test mode for 195/65R15 91V type tire Hankook of a passenger car.The results show that the LSCF method is much better than the LSCE method in the low frequency field,specially in the middle and high frequency field. |
