过去对于在动荷载作用下结构振动的分析做了很多工作.但是,对于有限个支座运动引起结构振动的分析,相对来说成果较少.1964年笔者在文中,讨论了有阻尼多自由度体系各支座发生不同运动所引起体系的强迫振动.该文曾在1965年中国建筑学会和土木工程学会联合召开的房屋结构和动力机械基础振动学术会议上提出.1971年日本学者青柳史郎也研究了相同的问题,其成果于1974年被编入著作、1980年被编入著作,并在工程设计中得到广泛地应用.青柳史郎所研究的问题和力学模型与笔者完全相同.但是,由于他列出的振动微分方程不成立,致使所得结果不正确(详见后面的讨论).
In the past, a lot of work has been done on the analysis of structural vibration under dynamic loading. However, the analysis of the structural vibration caused by a limited number of bearings has relatively few results. In 1964, the author discussed the damped multi-degrees of freedom in the paper. The forced vibration of the system caused by different movements of each support of the system. This article was presented at the Academic Conference on Building Structure and Power Machinery Foundation Vibration Jointly Held by the Chinese Society of Architects and the Society of Civil Engineers in 1965. In 1971, Japanese scholar Shiori Shiro also studied. The same problem, the results of which were incorporated into the work in 1974, was incorporated into the work in 1980, and was widely used in engineering design. The problems and mechanics models studied by Shiraki Shiro are exactly the same as the author. However, due to his The listed vibrational differential equations do not hold, resulting in incorrect results (see later discussion).
