用模态综合模型对制动器噪声进行模拟分析与抑制
CHINESE JOURNAL OF AUTOMOTIVE ENGINEERING(2021)
Abstract
综述了对于制动器噪声问题能进行较为有效控制且得到应用的研究技术成果,利用在研究制动器噪声问题发生机理的基础上发展的系统模态综合模型分析方法,对一个存在低频噪声的制动器进行了分析.找出了影响噪声发生的关键构件是制动器支架,对其进行了改进设计,通过按照SAE J2521标准进行的台架试验,证明其有效性,并将原制动器按SAE J2521标准属于BBB-BB级之间的产品,提升到AAA级的顶级标准.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
