Abstract

The peculiarity of offshore cranes, i. e. cranes based on ships or drilling platforms, is not only a significant motion of their base, but also the taut-slack phenomenon. Under some circumstances a rope can temporarily go completely slack, while a moment later, the force in the rope can increase to nominal or even higher value. Periodic occurrence of such phenomena can be damaging to the supporting structure of the crane and its driver. In the paper, mathematical models of offshore cranes that allow for analysis of the taut-slack phenomenon are presented. Results of numerical calculations show that the method of load stabilization proposed by the authors in their earlier works can eliminate this problem.

海上起重机载荷定位稳定化对绳索紧松现象的影响

海上起重机(即基于船舶或钻井平台的起重机)的特点不仅在于其基座有明显的运动，而且还存在紧-松现象。在某些情况下，绳子可以暂时完全松弛，而片刻之后，绳子上的力可以增加到标称值甚至更高的值。这种现象的周期性发生会对起重机的支撑结构及其驾驶员造成破坏。本文建立了海上起重机的数学模型，分析了海上起重机的松紧现象。数值计算结果表明，作者在其早期工作中提出的负荷稳定方法可以消除这一问题。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
