试论钻杆柱的随机振动

鉴于目前钻杆柱振动理论有较大的局限性,本文引用新近发展起来的随机振动理论研究钻杆柱的振动。笔者认为钻杆柱的振动属随机振动。在大量试验数据基础上,随机振动的统计分析特性具有较大的实用价值。

ON THE RANDOM VIBRATION OF DRILLING LINE

The theoretical research in the vibration of drilling line has a large limitation because it is based on the traditional theory of vibration. This paper first indicates that the vibration of a drilling line should be random vibration, and introduces the theory of random vibration into the research of the vibration of drilling line, which has been developed in recent 30 years. The properties of statistical analysis of random vibration would be of great practical use and economic value. This research must base on a large number of data obtained in the test.
