以典型的制动尖叫为例,针对摩擦引起的振动和噪声问题从试验研究与分析、发生机理与理论、建模方法与仿真3个方面对国内外的研究进展进行了综述.在分析讨论主要研究困难和前期工作缺陷的基础上提出考虑系统参数的随机性、开展摩擦噪声不确定性研究的建议.
A comprehensive technical review on friction- induced vibration and noise is conducted from the aspects of experimental analysis, generation mechanisms, modeling methods and prediction by taking the automotive brake squeal as an example. On the basis of a discussion on difficulties and shortcomings of the former research, a proposal was put forward for an uncertainty research on frictional oscillation and acoustics by taking into account the stochastic parameters.
