摘要
机械强度与振动问题普遍存在于我国重大工程建设中,因此客观地评价我国在该领域的技术发展水平具有非常重要的现实意义。首先阐述机械强度与振动的相关性,然后论述重大工程中一些机械强度与振动问题。进而通过研究比较各个国家近十年来在该领域所发表文献的变化趋势,分析我国在此领域的发展现状。我国相关论文的增长趋势在国际上占有绝对的优势,但高水平论文相对还较少,各个方面的发展不均衡。由此看来,为了提高我国在该领域的科技发展水平,有效促进国民经济的发展,仍需加强理论基础研究和应用基础研究。
Since mechanical strength and vibration problems exist universally in Chinese critical engineering projects, it＇s practically meaningful to objectively evaluate the technology development level of China in this field. Firstly, the correlations of vibration and mechanical strength are described. Secondly, the development level of mechanical strength and vibration in several critical projects are discussed. Then by comparing paper numbers of several countries in recent ten years in the mechanical strength and vibration field, the development level of China in this field is analyzed. It can be concluded that the increasing speed of China in this field is absolutely superior to other countries. However, high level papers are relatively fewer, and some subdomains have developed out of balance. Therefore, to enhance the development level of China in this field and facilitate the national economic development, it is essential to strengthen the fundamental research and application research.
