当今世界，汽车工业已成为国民经济发展的重要支柱产业之一，而面对激烈竞争的汽车市场，除了提高汽车的各项性能指标和经济指标外，改善汽车排放，降低汽车振动与噪声，提高汽车舒适度已成为现代汽车设计及新技术开发研究的一个重要方面。本课程的主要任务是使学生了解并掌握形起汽车振动与噪声的主要激励源；单自由度及多单自由度振动的基本振动特性；汽车结构的模态分析；双层隔振的原理及参数的优化以及如何采取有效措施来减小振动和降低噪声。 通过本课程的学习，能培养学生对工程实际问题的观察、分析及解决问题的能力，为从事专业研究及毕业论文的开展，打下坚实的基础。

Nowadays, automobile industry has been one of important strut industries for the development of national economics. In order to face the drastically competed automobile industry markets, besides improving all kinds of automobile performance parameters, improving automobile emissions, decreasing automobile vibration and noise and improving automobile comfort have been one of important aspects of the research and development for the modern automobile design and new technology. The main task of this course is to make students know and master the main compelling origins which cause automobile vibration and noise, the basic vibration characteristics of one-freeness and multi-freeness vibration, model analysis for automotive structures, the principle of double layers insulating vibration, parameters optimization, and the effective measures to decrease automobile vibration and noise. From the study of this course, students' ability to observe practical engineering problems and analyze and solve problems can be cultivated, providing a stron
