摘要
汽车空气动力特性对汽车的动力性、经济性、操作稳定性和舒适性有着重要影响,为总结汽车空气动力特性的研究现状和发展趋势,通过使用CiteSpace可视化文献计量工具对汽车空气动力特性进行图谱分析。以2000—2022年中国知网(CNKI)数据库中收录的有关汽车空气动力特性的中文文献作为数据样本,对年份发文量、期刊来源类别、研究机构、学者以及关键词进行可视化分析,并生成相关的网络图谱。结果表明:以“汽车空气动力特性”为主题的研究持续受到学术界的关注,该领域的研究对相关重点实验室具有一定的依赖性,未来研究仍着眼于气动阻力、侧风稳定性和气动噪声方向,提出3种有重要研究意义的降低气动阻力方法,表明侧风稳定性的研究具有重要意义,主动控制方法及空气射流方法已经成为降低气动噪声值得探索的新途径。
The aerodynamic characteristics of automobiles have important influences on the power, economy,operation stability and comforts of automobiles. In order to summarize the research status and development trends of automobile aerodynamic characteristics, the CiteSpace, a visualization bibliometrics tool, is applied to analyze the spectrums of automobile aerodynamic characteristics.The Chinese literatures on the aerodynamic characteristics of automobiles included in the China Knowledge Network(CNKI) database from 2000 to 2022 were utilized as data sample to visualize and analyze the chronological publication volumes, journal source categories, research institutions, scholars and key words to generate relevant network graphs.The results show that research on the topic of“Automotive Aerodynamics”has been continue to receive academic attention, research in this area has been depending on the relevant key laboratories, future research will be still focusing on aerodynamic drags, crosswind stabilities and aerodynamic noises. 3 important methods to reduce aerodynamic drag are proposed. It is shown that the importance of studying crosswind stability and active control method and air jet method are new ways, which are worth of exploring for reducing aerodynamic noises.
